+Helper functions around Function call/apply/bind, for use in `call-bind`.
+
+The only packages that should likely ever use this package directly are `call-bind` and `get-intrinsic`.
+Please use `call-bind` unless you have a very good reason not to.
+
+## Getting started
+
+```sh
+npm install --save call-bind-apply-helpers
+```
+
+## Usage/Examples
+
+```js
+const assert = require('assert');
+const callBindBasic = require('call-bind-apply-helpers');
+
+function f(a, b) {
+	assert.equal(this, 1);
+	assert.equal(a, 2);
+	assert.equal(b, 3);
+	assert.equal(arguments.length, 2);
+}
+
+const fBound = callBindBasic([f, 1]);
+
+delete Function.prototype.call;
+delete Function.prototype.bind;
+
+fBound(2, 3);
+```
+
+## Tests
+
+Clone the repo, `npm install`, and run `npm test`

+
+Creative Commons public licenses provide a standard set of terms and

+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not
+exhaustive, and do not form part of our licenses.
+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms
+     and conditions of the license they choose before applying it.
+     Licensors should also secure all rights necessary before
+     applying our licenses so that the public can reuse the
+     material as expected. Licensors should clearly mark any
+     material not subject to the license. This includes other CC-

+
+     Considerations for the public: By using one of our public
+     licenses, a licensor grants the public permission to use the
+     licensed material under specified terms and conditions. If
+     the licensor's permission is not necessary for any reason--for
+     example, because of any applicable exception or limitation to

+     rights in the material. A licensor may make special requests,
+     such as asking that all changes be marked or described.
+     Although not required by our licenses, you are encouraged to
+     respect those requests where reasonable. More_considerations

+
+By exercising the Licensed Rights (defined below), You accept and agree
+to be bound by the terms and conditions of this Creative Commons
+Attribution 4.0 International Public License ("Public License"). To the
+extent this Public License may be interpreted as a contract, You are
+granted the Licensed Rights in consideration of Your acceptance of
+these terms and conditions, and the Licensor grants You such rights in
+consideration of benefits the Licensor receives from making the
+Licensed Material available under these terms and conditions.
+
+
+Section 1 -- Definitions.
+
+  a. Adapted Material means material subject to Copyright and Similar
+     Rights that is derived from or based upon the Licensed Material
+     and in which the Licensed Material is translated, altered,
+     arranged, transformed, or otherwise modified in a manner requiring
+     permission under the Copyright and Similar Rights held by the
+     Licensor. For purposes of this Public License, where the Licensed
+     Material is a musical work, performance, or sound recording,
+     Adapted Material is always produced where the Licensed Material is
+     synched in timed relation with a moving image.
+
+  b. Adapter's License means the license You apply to Your Copyright
+     and Similar Rights in Your contributions to Adapted Material in
+     accordance with the terms and conditions of this Public License.
+
+  c. Copyright and Similar Rights means copyright and/or similar rights
+     closely related to copyright including, without limitation,
+     performance, broadcast, sound recording, and Sui Generis Database
+     Rights, without regard to how the rights are labeled or
+     categorized. For purposes of this Public License, the rights
+     specified in Section 2(b)(1)-(2) are not Copyright and Similar
+     Rights.
+
+  d. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws
+     fulfilling obligations under Article 11 of the WIPO Copyright
+     Treaty adopted on December 20, 1996, and/or similar international
+     agreements.
+
+  e. Exceptions and Limitations means fair use, fair dealing, and/or
+     any other exception or limitation to Copyright and Similar Rights
+     that applies to Your use of the Licensed Material.
+
+  f. Licensed Material means the artistic or literary work, database,
+     or other material to which the Licensor applied this Public
+     License.
+
+  g. Licensed Rights means the rights granted to You subject to the
+     terms and conditions of this Public License, which are limited to
+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  h. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  i. Share means to provide material to the public by any means or
+     process that requires permission under the Licensed Rights, such
+     as reproduction, public display, public performance, distribution,
+     dissemination, communication, or importation, and to make material
+     available to the public including in ways that members of the
+     public may access the material from a place and at a time
+     individually chosen by them.
+
+  j. Sui Generis Database Rights means rights other than copyright
+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

+
+[![npm](https://img.shields.io/npm/v/csstype.svg)](https://www.npmjs.com/package/csstype)
+
+TypeScript and Flow definitions for CSS, generated by [data from MDN](https://github.com/mdn/data). It provides autocompletion and type checking for CSS properties and values.
+
+**TypeScript**
+
+```ts
+import type * as CSS from 'csstype';
+
+const style: CSS.Properties = {
+  colour: 'white', // Type error on property
+  textAlign: 'middle', // Type error on value
+};
+```
+
+**Flow**
+
+```js
+// @flow strict
+import * as CSS from 'csstype';
+
+const style: CSS.Properties<> = {
+  colour: 'white', // Type error on property
+  textAlign: 'middle', // Type error on value
+};
+```
+
+_Further examples below will be in TypeScript!_
+
+## Getting started
+
+```sh
+$ npm install csstype
+```

+
+## Style types
+
+Properties are categorized in different uses and in several technical variations to provide typings that suits as many as possible.
+
+|                | Default              | `Hyphen`                   | `Fallback`                   | `HyphenFallback`                   |
+| -------------- | -------------------- | -------------------------- | ---------------------------- | ---------------------------------- |
+| **All**        | `Properties`         | `PropertiesHyphen`         | `PropertiesFallback`         | `PropertiesHyphenFallback`         |
+| **`Standard`** | `StandardProperties` | `StandardPropertiesHyphen` | `StandardPropertiesFallback` | `StandardPropertiesHyphenFallback` |
+| **`Vendor`**   | `VendorProperties`   | `VendorPropertiesHyphen`   | `VendorPropertiesFallback`   | `VendorPropertiesHyphenFallback`   |
+| **`Obsolete`** | `ObsoleteProperties` | `ObsoletePropertiesHyphen` | `ObsoletePropertiesFallback` | `ObsoletePropertiesHyphenFallback` |
+| **`Svg`**      | `SvgProperties`      | `SvgPropertiesHyphen`      | `SvgPropertiesFallback`      | `SvgPropertiesHyphenFallback`      |
+
+Categories:
+
+- **All** - Includes `Standard`, `Vendor`, `Obsolete` and `Svg`
+- **`Standard`** - Current properties and extends subcategories `StandardLonghand` and `StandardShorthand` _(e.g. `StandardShorthandProperties`)_
+- **`Vendor`** - Vendor prefixed properties and extends subcategories `VendorLonghand` and `VendorShorthand` _(e.g. `VendorShorthandProperties`)_
+- **`Obsolete`** - Removed or deprecated properties
+- **`Svg`** - SVG-specific properties
+
+Variations:
+
+- **Default** - JavaScript (camel) cased property names
+- **`Hyphen`** - CSS (kebab) cased property names
+- **`Fallback`** - Also accepts array of values e.g. `string | string[]`
+
+## At-rule types
+
+At-rule interfaces with descriptors.
+
+**TypeScript**: These will be found in the `AtRule` namespace, e.g. `AtRule.Viewport`.  
+**Flow**: These will be prefixed with `AtRule$`, e.g. `AtRule$Viewport`.
+
+|                      | Default        | `Hyphen`             | `Fallback`             | `HyphenFallback`             |
+| -------------------- | -------------- | -------------------- | ---------------------- | ---------------------------- |
+| **`@counter-style`** | `CounterStyle` | `CounterStyleHyphen` | `CounterStyleFallback` | `CounterStyleHyphenFallback` |
+| **`@font-face`**     | `FontFace`     | `FontFaceHyphen`     | `FontFaceFallback`     | `FontFaceHyphenFallback`     |
+| **`@viewport`**      | `Viewport`     | `ViewportHyphen`     | `ViewportFallback`     | `ViewportHyphenFallback`     |
+
+## Pseudo types
+
+String literals of pseudo classes and pseudo elements
+
+- `Pseudos`
+
+  Extends:
+  - `AdvancedPseudos`
+
+    Function-like pseudos e.g. `:not(:first-child)`. The string literal contains the value excluding the parenthesis: `:not`. These are separated because they require an argument that results in infinite number of variations.
+
+  - `SimplePseudos`
+
+    Plain pseudos e.g. `:hover` that can only be **one** variation.
+
+## Generics
+
+All interfaces has two optional generic argument to define length and time: `CSS.Properties<TLength = string | 0, TTime = string>`
+
+- **Length** is the first generic parameter and defaults to `string | 0` because `0` is the only [length where the unit identifier is optional](https://drafts.csswg.org/css-values-3/#lengths). You can specify this, e.g. `string | number`, for platforms and libraries that accepts any numeric value as length with a specific unit.
+  ```tsx
+  const style: CSS.Properties<string | number> = {
+    width: 100,
+  };
+  ```
+- **Time** is the second generic argument and defaults to `string`. You can specify this, e.g. `string | number`, for platforms and libraries that accepts any numeric value as length with a specific unit.
+  ```tsx
+  const style: CSS.Properties<string | number, number> = {
+    transitionDuration: 1000,
+  };
+  ```
+
+## Usage
+
+```ts
+import type * as CSS from 'csstype';
+
+const style: CSS.Properties = {
+  width: '10px',
+  margin: '1em',
+};
+```
+
+In some cases, like for CSS-in-JS libraries, an array of values is a way to provide fallback values in CSS. Using `CSS.PropertiesFallback` instead of `CSS.Properties` will add the possibility to use any property value as an array of values.
+
+```ts
+import type * as CSS from 'csstype';
+
+const style: CSS.PropertiesFallback = {
+  display: ['-webkit-flex', 'flex'],
+  color: 'white',
+};
+```
+
+There's even string literals for pseudo selectors and elements.
+
+```ts
+import type * as CSS from 'csstype';
+
+const pseudos: { [P in CSS.SimplePseudos]?: CSS.Properties } = {
+  ':hover': {
+    display: 'flex',
+  },
+};
+```
+
+Hyphen cased (kebab cased) properties are provided in `CSS.PropertiesHyphen` and `CSS.PropertiesHyphenFallback`. It's not **not** added by default in `CSS.Properties`. To allow both of them, you can simply extend with `CSS.PropertiesHyphen` or/and `CSS.PropertiesHyphenFallback`.
+
+```ts
+import type * as CSS from 'csstype';
+
+interface Style extends CSS.Properties, CSS.PropertiesHyphen {}
+
+const style: Style = {
+  'flex-grow': 1,
+  'flex-shrink': 0,
+  'font-weight': 'normal',
+  backgroundColor: 'white',
+};
+```
+
+Adding type checked CSS properties to a `HTMLElement`.
+
+```ts
+import type * as CSS from 'csstype';
+
+const style: CSS.Properties = {
+  color: 'red',
+  margin: '1em',
+};
+
+let button = document.createElement('button');
+
+Object.assign(button.style, style);
+```
+
+## What should I do when I get type errors?
+
+The goal is to have as perfect types as possible and we're trying to do our best. But with CSS Custom Properties, the CSS specification changing frequently and vendors implementing their own specifications with new releases sometimes causes type errors even if it should work. Here's some steps you could take to get it fixed:
+
+_If you're using CSS Custom Properties you can step directly to step 3._
+
+1.  **First of all, make sure you're doing it right.** A type error could also indicate that you're not :wink:
+    - Some CSS specs that some vendors has implemented could have been officially rejected or haven't yet received any official acceptance and are therefor not included
+    - If you're using TypeScript, [type widening](https://blog.mariusschulz.com/2017/02/04/TypeScript-2-1-literal-type-widening) could be the reason you get `Type 'string' is not assignable to...` errors
+
+2.  **Have a look in [issues](https://github.com/frenic/csstype/issues) to see if an issue already has been filed. If not, create a new one.** To help us out, please refer to any information you have found.
+3.  Fix the issue locally with **TypeScript** (Flow further down):
+    - The recommended way is to use **module augmentation**. Here's a few examples:
+
+      ```ts
+      // My css.d.ts file
+      import type * as CSS from 'csstype';
+
+      declare module 'csstype' {
+        interface Properties {
+          // Add a missing property
+          WebkitRocketLauncher?: string;
+
+          // Add a CSS Custom Property
+          '--theme-color'?: 'black' | 'white';
+
+          // Allow namespaced CSS Custom Properties
+          [index: `--theme-${string}`]: any;
+
+          // Allow any CSS Custom Properties
+          [index: `--${string}`]: any;
+
+          // ...or allow any other property
+          [index: string]: any;
+        }
+      }
+      ```
+
+    - The alternative way is to use **type assertion**. Here's a few examples:
+
+      ```ts
+      const style: CSS.Properties = {
+        // Add a missing property
+        ['WebkitRocketLauncher' as any]: 'launching',
+
+        // Add a CSS Custom Property
+        ['--theme-color' as any]: 'black',
+      };
+      ```
+
+    Fix the issue locally with **Flow**:
+    - Use **type assertion**. Here's a few examples:
+
+      ```js
+      const style: $Exact<CSS.Properties<*>> = {
+        // Add a missing property
+        [('WebkitRocketLauncher': any)]: 'launching',
+
+        // Add a CSS Custom Property
+        [('--theme-color': any)]: 'black',
+      };
+      ```
+
+## Version 3.2
+
+- **No longer compatible with version 2**  
+  Conflicts may occur when both version ^3.2.0 and ^2.0.0 are installed. Potential fix for Npm would be to force resolution in `package.json`:
+  ```json
+  {
+    "overrides": {
+      "csstype": "^3.2.0"
+    }
+  }
+  ```
+
+## Version 3.1
+
+- **Data types are exposed**  
+  TypeScript: `DataType.Color`
+  Flow: `DataType$Color`
+
+## Version 3.0
+
+- **All property types are exposed with namespace**  
+  TypeScript: `Property.AlignContent` (was `AlignContentProperty` before)  
+  Flow: `Property$AlignContent`
+- **All at-rules are exposed with namespace**  
+  TypeScript: `AtRule.FontFace` (was `FontFace` before)  
+  Flow: `AtRule$FontFace`
+- **Data types are NOT exposed**  
+  E.g. `Color` and `Box`. Because the generation of data types may suddenly be removed or renamed.
+- **TypeScript hack for autocompletion**  
+  Uses `(string & {})` for literal string unions and `(number & {})` for literal number unions ([related issue](https://github.com/microsoft/TypeScript/issues/29729)). Utilize `PropertyValue<T>` to unpack types from e.g. `(string & {})` to `string`.
+- **New generic for time**  
+  Read more on the ["Generics"](#generics) section.
+- **Flow types improvements**  
+  Flow Strict enabled and exact types are used.
+
+## Contributing
+
+**Never modify `index.d.ts` and `index.js.flow` directly. They are generated automatically and committed so that we can easily follow any change it results in.** Therefor it's important that you run `$ git config merge.ours.driver true` after you've forked and cloned. That setting prevents merge conflicts when doing rebase.
+
+### Commands
+
+- `npm run build` Generates typings and type checks them
+- `npm run watch` Runs build on each save
+- `npm run test` Runs the tests
+- `npm run lazy` Type checks, lints and formats everything

+# d3-color
+
+Even though your browser understands a lot about colors, it doesn’t offer much help in manipulating colors through JavaScript. The d3-color module therefore provides representations for various color spaces, allowing specification, conversion and manipulation. (Also see [d3-interpolate](https://github.com/d3/d3-interpolate) for color interpolation.)
+
+For example, take the color named “steelblue”:
+
+```js
+const c = d3.color("steelblue"); // {r: 70, g: 130, b: 180, opacity: 1}
+```
+
+Let’s try converting it to HSL:
+
+```js
+const c = d3.hsl("steelblue"); // {h: 207.27…, s: 0.44, l: 0.4902…, opacity: 1}
+```
+
+Now rotate the hue by 90°, bump up the saturation, and format as a string for CSS:
+
+```js
+c.h += 90;
+c.s += 0.2;
+c + ""; // rgb(198, 45, 205)
+```
+
+To fade the color slightly:
+
+```js
+c.opacity = 0.8;
+c + ""; // rgba(198, 45, 205, 0.8)
+```
+
+In addition to the ubiquitous and machine-friendly [RGB](#rgb) and [HSL](#hsl) color space, d3-color supports color spaces that are designed for humans:
+
+* [CIELAB](#lab) (*a.k.a.* “Lab”)
+* [CIELCh<sub>ab</sub>](#lch) (*a.k.a.* “LCh” or “HCL”)
+* Dave Green’s [Cubehelix](#cubehelix)
+
+Cubehelix features monotonic lightness, while CIELAB and its polar form CIELCh<sub>ab</sub> are perceptually uniform.
+
+## Extensions
+
+For additional color spaces, see:
+
+* [d3-cam16](https://github.com/d3/d3-cam16)
+* [d3-cam02](https://github.com/connorgr/d3-cam02)
+* [d3-hsv](https://github.com/d3/d3-hsv)
+* [d3-hcg](https://github.com/d3/d3-hcg)
+* [d3-hsluv](https://github.com/petulla/d3-hsluv)
+
+To measure color differences, see:
+
+* [d3-color-difference](https://github.com/Evercoder/d3-color-difference)
+
+## Installing
+
+If you use npm, `npm install d3-color`. You can also download the [latest release on GitHub](https://github.com/d3/d3-color/releases/latest). For vanilla HTML in modern browsers, import d3-color from Skypack:
+
+```html
+<script type="module">
+
+import {rgb} from "https://cdn.skypack.dev/d3-color@3";
+
+const steelblue = d3.rgb("steelblue");
+
+</script>
+```
+
+For legacy environments, you can load d3-color’s UMD bundle from an npm-based CDN such as jsDelivr; a `d3` global is exported:
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/d3-color@3"></script>
+<script>
+
+const steelblue = d3.rgb("steelblue");
+
+</script>
+```
+
+[Try d3-color in your browser.](https://observablehq.com/collection/@d3/d3-color)
+
+## API Reference
+
+<a name="color" href="#color">#</a> d3.<b>color</b>(<i>specifier</i>) [<>](https://github.com/d3/d3-color/blob/master/src/color.js "Source")
+
+Parses the specified [CSS Color Module Level 3](http://www.w3.org/TR/css3-color/#colorunits) *specifier* string, returning an [RGB](#rgb) or [HSL](#hsl) color, along with [CSS Color Module Level 4 hex](https://www.w3.org/TR/css-color-4/#hex-notation) *specifier* strings. If the specifier was not valid, null is returned. Some examples:
+
+* `rgb(255, 255, 255)`
+* `rgb(10%, 20%, 30%)`
+* `rgba(255, 255, 255, 0.4)`
+* `rgba(10%, 20%, 30%, 0.4)`
+* `hsl(120, 50%, 20%)`
+* `hsla(120, 50%, 20%, 0.4)`
+* `#ffeeaa`
+* `#fea`
+* `#ffeeaa22`
+* `#fea2`
+* `steelblue`
+
+The list of supported [named colors](http://www.w3.org/TR/SVG/types.html#ColorKeywords) is specified by CSS.
+
+Note: this function may also be used with `instanceof` to test if an object is a color instance. The same is true of color subclasses, allowing you to test whether a color is in a particular color space.
+
+<a name="color_opacity" href="#color_opacity">#</a> *color*.<b>opacity</b>
+
+This color’s opacity, typically in the range [0, 1].
+
+<a name="color_rgb" href="#color_rgb">#</a> *color*.<b>rgb</b>() [<>](https://github.com/d3/d3-color/blob/master/src/color.js "Source")
+
+Returns the [RGB equivalent](#rgb) of this color. For RGB colors, that’s `this`.
+
+<a name="color_copy" href="#color_copy">#</a> <i>color</i>.<b>copy</b>([<i>values</i>]) [<>](https://github.com/d3/d3-color/blob/master/src/color.js "Source")
+
+Returns a copy of this color. If *values* is specified, any enumerable own properties of *values* are assigned to the new returned color. For example, to derive a copy of a *color* with opacity 0.5, say
+
+```js
+color.copy({opacity: 0.5})
+```
+
+<a name="color_brighter" href="#color_brighter">#</a> *color*.<b>brighter</b>([<i>k</i>]) [<>](https://github.com/d3/d3-color/blob/master/src/color.js "Source")
+
+Returns a brighter copy of this color. If *k* is specified, it controls how much brighter the returned color should be. If *k* is not specified, it defaults to 1. The behavior of this method is dependent on the implementing color space.
+
+<a name="color_darker" href="#color_darker">#</a> *color*.<b>darker</b>([<i>k</i>]) [<>](https://github.com/d3/d3-color/blob/master/src/color.js "Source")
+
+Returns a darker copy of this color. If *k* is specified, it controls how much darker the returned color should be. If *k* is not specified, it defaults to 1. The behavior of this method is dependent on the implementing color space.
+
+<a name="color_displayable" href="#color_displayable">#</a> *color*.<b>displayable</b>() [<>](https://github.com/d3/d3-color/blob/master/src/color.js "Source")
+

+# d3-ease
+
+*Easing* is a method of distorting time to control apparent motion in animation. It is most commonly used for [slow-in, slow-out](https://en.wikipedia.org/wiki/12_basic_principles_of_animation#Slow_In_and_Slow_Out). By easing time, [animated transitions](https://github.com/d3/d3-transition) are smoother and exhibit more plausible motion.
+
+The easing types in this module implement the [ease method](#ease_ease), which takes a normalized time *t* and returns the corresponding “eased” time *tʹ*. Both the normalized time and the eased time are typically in the range [0,1], where 0 represents the start of the animation and 1 represents the end; some easing types, such as [elastic](#easeElastic), may return eased times slightly outside this range. A good easing type should return 0 if *t* = 0 and 1 if *t* = 1. See the [easing explorer](https://observablehq.com/@d3/easing) for a visual demonstration.
+
+These easing types are largely based on work by [Robert Penner](http://robertpenner.com/easing/).
+
+## Installing
+
+If you use npm, `npm install d3-ease`. You can also download the [latest release on GitHub](https://github.com/d3/d3-ease/releases/latest). For vanilla HTML in modern browsers, import d3-ease from Skypack:
+
+```html
+<script type="module">
+
+import {easeCubic} from "https://cdn.skypack.dev/d3-ease@3";
+
+const e = easeCubic(0.25);
+
+</script>
+```
+
+For legacy environments, you can load d3-ease’s UMD bundle from an npm-based CDN such as jsDelivr; a `d3` global is exported:
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/d3-ease@3"></script>
+<script>
+
+const e = d3.easeCubic(0.25);
+
+</script>
+```
+
+[Try d3-ease in your browser.](https://observablehq.com/@d3/easing-animations)
+
+## API Reference
+
+<a name="_ease" href="#_ease">#</a> <i>ease</i>(<i>t</i>)
+
+Given the specified normalized time *t*, typically in the range [0,1], returns the “eased” time *tʹ*, also typically in [0,1]. 0 represents the start of the animation and 1 represents the end. A good implementation returns 0 if *t* = 0 and 1 if *t* = 1. See the [easing explorer](https://observablehq.com/@d3/easing) for a visual demonstration. For example, to apply [cubic](#easeCubic) easing:
+
+```js
+const te = d3.easeCubic(t);
+```
+
+Similarly, to apply custom [elastic](#easeElastic) easing:
+
+```js
+// Before the animation starts, create your easing function.
+const customElastic = d3.easeElastic.period(0.4);
+
+// During the animation, apply the easing function.
+const te = customElastic(t);

+# d3-interpolate
+
+This module provides a variety of interpolation methods for blending between two values. Values may be numbers, colors, strings, arrays, or even deeply-nested objects. For example:
+
+```js
+const i = d3.interpolateNumber(10, 20);
+i(0.0); // 10
+i(0.2); // 12
+i(0.5); // 15
+i(1.0); // 20
+```
+
+The returned function `i` is called an *interpolator*. Given a starting value *a* and an ending value *b*, it takes a parameter *t* in the domain [0, 1] and returns the corresponding interpolated value between *a* and *b*. An interpolator typically returns a value equivalent to *a* at *t* = 0 and a value equivalent to *b* at *t* = 1.
+
+You can interpolate more than just numbers. To find the perceptual midpoint between steelblue and brown:
+
+```js
+d3.interpolateLab("steelblue", "brown")(0.5); // "rgb(142, 92, 109)"
+```
+
+Here’s a more elaborate example demonstrating type inference used by [interpolate](#interpolate):
+
+```js
+const i = d3.interpolate({colors: ["red", "blue"]}, {colors: ["white", "black"]});
+i(0.0); // {colors: ["rgb(255, 0, 0)", "rgb(0, 0, 255)"]}
+i(0.5); // {colors: ["rgb(255, 128, 128)", "rgb(0, 0, 128)"]}
+i(1.0); // {colors: ["rgb(255, 255, 255)", "rgb(0, 0, 0)"]}
+```
+
+Note that the generic value interpolator detects not only nested objects and arrays, but also color strings and numbers embedded in strings!
+
+## Installing
+
+If you use npm, `npm install d3-interpolate`. You can also download the [latest release on GitHub](https://github.com/d3/d3-interpolate/releases/latest). For vanilla HTML in modern browsers, import d3-interpolate from Skypack:
+
+```html
+<script type="module">
+
+import {interpolateRgb} from "https://cdn.skypack.dev/d3-interpolate@3";
+
+const interpolate = interpolateRgb("steelblue", "brown");
+
+</script>
+```
+
+For legacy environments, you can load d3-interpolate’s UMD bundle from an npm-based CDN such as jsDelivr; a `d3` global is exported. (If using [color interpolation](#color-spaces), also load [d3-color](https://github.com/d3/d3-color).)
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/d3-color@3"></script>
+<script src="https://cdn.jsdelivr.net/npm/d3-interpolate@3"></script>
+<script>
+
+const interpolate = d3.interpolateRgb("steelblue", "brown");
+
+</script>
+```

+## API Reference
+
+<a name="interpolate" href="#interpolate">#</a> d3.<b>interpolate</b>(<i>a</i>, <i>b</i>) · [Source](https://github.com/d3/d3-interpolate/blob/master/src/value.js), [Examples](https://observablehq.com/@d3/d3-interpolate)
+
+Returns an interpolator between the two arbitrary values *a* and *b*. The interpolator implementation is based on the type of the end value *b*, using the following algorithm:
+
+1. If *b* is null, undefined or a boolean, use the constant *b*.
+2. If *b* is a number, use [interpolateNumber](#interpolateNumber).
+3. If *b* is a [color](https://github.com/d3/d3-color/blob/master/README.md#color) or a string coercible to a color, use [interpolateRgb](#interpolateRgb).
+4. If *b* is a [date](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date), use [interpolateDate](#interpolateDate).
+5. If *b* is a string, use [interpolateString](#interpolateString).
+6. If *b* is a [typed array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray) of numbers, use [interpolateNumberArray](#interpolateNumberArray).
+7. If *b* is a generic [array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/isArray), use [interpolateArray](#interpolateArray).
+8. If *b* is coercible to a number, use [interpolateNumber](#interpolateNumber).
+9. Use [interpolateObject](#interpolateObject).
+
+Based on the chosen interpolator, *a* is coerced to the suitable corresponding type.
+
+<a name="interpolateNumber" href="#interpolateNumber">#</a> d3.<b>interpolateNumber</b>(<i>a</i>, <i>b</i>) · [Source](https://github.com/d3/d3-interpolate/blob/master/src/number.js), [Examples](https://observablehq.com/@d3/d3-interpolatenumber)
+
+Returns an interpolator between the two numbers *a* and *b*. The returned interpolator is equivalent to:
+
+```js
+function interpolator(t) {
+  return a * (1 - t) + b * t;
+}
+```
+
+Caution: avoid interpolating to or from the number zero when the interpolator is used to generate a string. When very small values are stringified, they may be converted to scientific notation, which is an invalid attribute or style property value in older browsers. For example, the number `0.0000001` is converted to the string `"1e-7"`. This is particularly noticeable with interpolating opacity. To avoid scientific notation, start or end the transition at 1e-6: the smallest value that is not stringified in scientific notation.

+
+Returns an interpolator between the two numbers *a* and *b*; the interpolator is similar to [interpolateNumber](#interpolateNumber), except it will round the resulting value to the nearest integer.
+
+<a name="interpolateString" href="#interpolateString">#</a> d3.<b>interpolateString</b>(<i>a</i>, <i>b</i>) · [Source](https://github.com/d3/d3-interpolate/blob/master/src/string.js), [Examples](https://observablehq.com/@d3/d3-interpolatestring)
+
+Returns an interpolator between the two strings *a* and *b*. The string interpolator finds numbers embedded in *a* and *b*, where each number is of the form understood by JavaScript. A few examples of numbers that will be detected within a string: `-1`, `42`, `3.14159`, and `6.0221413e+23`.
+
+For each number embedded in *b*, the interpolator will attempt to find a corresponding number in *a*. If a corresponding number is found, a numeric interpolator is created using [interpolateNumber](#interpolateNumber). The remaining parts of the string *b* are used as a template: the static parts of the string *b* remain constant for the interpolation, with the interpolated numeric values embedded in the template.
+
+For example, if *a* is `"300 12px sans-serif"`, and *b* is `"500 36px Comic-Sans"`, two embedded numbers are found. The remaining static parts (of string *b*) are a space between the two numbers (`" "`), and the suffix (`"px Comic-Sans"`). The result of the interpolator at *t* = 0.5 is `"400 24px Comic-Sans"`.
+
+<a name="interpolateDate" href="#interpolateDate">#</a> d3.<b>interpolateDate</b>(<i>a</i>, <i>b</i>) · [Source](https://github.com/d3/d3-interpolate/blob/master/src/date.js), [Examples](https://observablehq.com/@d3/d3-interpolatedate)
+
+Returns an interpolator between the two [dates](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) *a* and *b*.
+
+Note: **no defensive copy** of the returned date is created; the same Date instance is returned for every evaluation of the interpolator. No copy is made for performance reasons; interpolators are often part of the inner loop of [animated transitions](https://github.com/d3/d3-transition).
+
+<a name="interpolateArray" href="#interpolateArray">#</a> d3.<b>interpolateArray</b>(<i>a</i>, <i>b</i>) · [Source](https://github.com/d3/d3-interpolate/blob/master/src/array.js), [Examples](https://observablehq.com/@d3/d3-interpolateobject)
+
+Returns an interpolator between the two arrays *a* and *b*. If *b* is a typed array (e.g., Float64Array), [interpolateNumberArray](#interpolateNumberArray) is called instead.
+
+Internally, an array template is created that is the same length as *b*. For each element in *b*, if there exists a corresponding element in *a*, a generic interpolator is created for the two elements using [interpolate](#interpolate). If there is no such element, the static value from *b* is used in the template. Then, for the given parameter *t*, the template’s embedded interpolators are evaluated. The updated array template is then returned.
+
+For example, if *a* is the array `[0, 1]` and *b* is the array `[1, 10, 100]`, then the result of the interpolator for *t* = 0.5 is the array `[0.5, 5.5, 100]`.
+
+Note: **no defensive copy** of the template array is created; modifications of the returned array may adversely affect subsequent evaluation of the interpolator. No copy is made for performance reasons; interpolators are often part of the inner loop of [animated transitions](https://github.com/d3/d3-transition).
+
+<a name="interpolateNumberArray" href="#interpolateNumberArray">#</a> d3.<b>interpolateNumberArray</b>(<i>a</i>, <i>b</i>) · [Source](https://github.com/d3/d3-interpolate/blob/master/src/numberArray.js), [Examples](https://observablehq.com/@d3/d3-interpolatenumberarray)
+
+Returns an interpolator between the two arrays of numbers *a* and *b*. Internally, an array template is created that is the same type and length as *b*. For each element in *b*, if there exists a corresponding element in *a*, the values are directly interpolated in the array template. If there is no such element, the static value from *b* is copied. The updated array template is then returned.
+
+Note: For performance reasons, **no defensive copy** is made of the template array and the arguments *a* and *b*; modifications of these arrays may affect subsequent evaluation of the interpolator.
+
+<a name="interpolateObject" href="#interpolateObject">#</a> d3.<b>interpolateObject</b>(<i>a</i>, <i>b</i>) · [Source](https://github.com/d3/d3-interpolate/blob/master/src/object.js), [Examples](https://observablehq.com/@d3/d3-interpolateobject)
+
+Returns an interpolator between the two objects *a* and *b*. Internally, an object template is created that has the same properties as *b*. For each property in *b*, if there exists a corresponding property in *a*, a generic interpolator is created for the two elements using [interpolate](#interpolate). If there is no such property, the static value from *b* is used in the template. Then, for the given parameter *t*, the template's embedded interpolators are evaluated and the updated object template is then returned.
+
+For example, if *a* is the object `{x: 0, y: 1}` and *b* is the object `{x: 1, y: 10, z: 100}`, the result of the interpolator for *t* = 0.5 is the object `{x: 0.5, y: 5.5, z: 100}`.
+
+Object interpolation is particularly useful for *dataspace interpolation*, where data is interpolated rather than attribute values. For example, you can interpolate an object which describes an arc in a pie chart, and then use [d3.arc](https://github.com/d3/d3-shape/blob/master/README.md#arc) to compute the new SVG path data.
+
+Note: **no defensive copy** of the template object is created; modifications of the returned object may adversely affect subsequent evaluation of the interpolator. No copy is made for performance reasons; interpolators are often part of the inner loop of [animated transitions](https://github.com/d3/d3-transition).

+
+Returns an interpolator between the two 2D CSS transforms represented by *a* and *b*. Each transform is decomposed to a standard representation of translate, rotate, *x*-skew and scale; these component transformations are then interpolated.

+
+Returns an interpolator between the two views *a* and *b* of a two-dimensional plane, based on [“Smooth and efficient zooming and panning”](http://www.win.tue.nl/~vanwijk/zoompan.pdf) by Jarke J. van Wijk and Wim A.A. Nuij. Each view is defined as an array of three numbers: *cx*, *cy* and *width*. The first two coordinates *cx*, *cy* represent the center of the viewport; the last coordinate *width* represents the size of the viewport.
+
+The returned interpolator exposes a *duration* property which encodes the recommended transition duration in milliseconds. This duration is based on the path length of the curved trajectory through *x,y* space. If you want a slower or faster transition, multiply this by an arbitrary scale factor (<i>V</i> as described in the original paper).

+

+
+Returns a discrete interpolator for the given array of *values*. The returned interpolator maps *t* in [0, 1 / *n*) to *values*[0], *t* in [1 / *n*, 2 / *n*) to *values*[1], and so on, where *n* = *values*.length. In effect, this is a lightweight [quantize scale](https://github.com/d3/d3-scale/blob/master/README.md#quantize-scales) with a fixed domain of [0, 1].

+
+Returns *n* uniformly-spaced samples from the specified *interpolator*, where *n* is an integer greater than one. The first sample is always at *t* = 0, and the last sample is always at *t* = 1. This can be useful in generating a fixed number of samples from a given interpolator, such as to derive the range of a [quantize scale](https://github.com/d3/d3-scale/blob/master/README.md#quantize-scales) from a [continuous interpolator](https://github.com/d3/d3-scale-chromatic/blob/master/README.md#interpolateWarm).
+
+Caution: this method will not work with interpolators that do not return defensive copies of their output, such as [d3.interpolateArray](#interpolateArray), [d3.interpolateDate](#interpolateDate) and [d3.interpolateObject](#interpolateObject). For those interpolators, you must wrap the interpolator and create a copy for each returned value.

+# dom-helpers
+
+tiny modular DOM lib for ie9+
+
+## Install
+
+```sh
+npm i -S dom-helpers
+```
+
+Mostly just naive wrappers around common DOM API inconsistencies, Cross browser work is minimal and mostly taken from jQuery. This library doesn't do a lot to normalize behavior across browsers, it mostly seeks to provide a common interface, and eliminate the need to write the same damn `if (ie9)` statements in every project.
+
+For example `on()` works in all browsers ie9+ but it uses the native event system so actual event oddities will continue to exist. If you need **robust** cross-browser support, use jQuery. If you are just tired of rewriting:
+
+```js
+if (document.addEventListener)
+  return (node, eventName, handler, capture) =>
+    node.addEventListener(eventName, handler, capture || false)
+else if (document.attachEvent)
+  return (node, eventName, handler) =>
+    node.attachEvent('on' + eventName, handler)
+```
+
+over and over again, or you need a ok `getComputedStyle` polyfill but don't want to include all of jQuery, use this.
+
+dom-helpers does expect certain, polyfillable, es5 features to be present for which you can use `es5-shim` where needed
+
+The real advantage to this collection is that any method can be required individually, meaning bundlers like webpack will only include the exact methods you use. This is great for environments where jQuery doesn't make sense, such as `React` where you only occasionally need to do direct DOM manipulation.
+
+All methods are exported as a flat namesapce

+- dom-helpers
+  - `ownerDocument(element)`: returns the element's document owner
+  - `ownerWindow(element)`: returns the element's document window
+  - `activeElement`: return focused element safely
+  - `querySelectorAll(element, selector)`: optimized qsa, uses `getElementBy{Id|TagName|ClassName}` if it can.
+  - `contains(container, element)`
+  - `height(element, useClientHeight)`
+  - `width(element, useClientWidth)`
+  - `matches(element, selector)`
+  - `offset(element)` -> `{ top: Number, left: Number, height: Number, width: Number}`
+  - `offsetParent(element)`: return the parent node that the element is offset from
+  - `position(element, [offsetParent]`: return "offset" of the node to its offsetParent, optionally you can specify the offset parent if different than the "real" one
+  - `scrollTop(element, [value])`
+  - `scrollLeft(element, [value])`
+  - `scrollParent(element)`
+  - `addClass(element, className)`
+  - `removeClass(element, className)`
+  - `hasClass(element, className)`
+  - `toggleClass(element, className)`
+  - `style(element, propName)` or `style(element, objectOfPropValues)`
+  - `getComputedStyle(element)` -> `getPropertyValue(name)`
+  - `animate(node, properties, duration, easing, callback)` programmatically start css transitions
+  - `transitionEnd(node, handler, [duration], [padding])` listens for transition end, and ensures that the handler if called even if the transition fails to fire its end event. Will attempt to read duration from the element, otherwise one can be provided
+  - `addEventListener(node, eventName, handler, [options])`:
+  - `removeEventListener(node, eventName, handler, [options])`:
+  - `listen(node, eventName, handler, [options])`: wraps `addEventlistener` and returns a function that calls `removeEventListener` for you
+  - `filter(selector, fn)`: returns a function handler that only fires when the target matches or is contained in the selector ex: `on(list, 'click', filter('li > a', handler))`
+  - `requestAnimationFrame(cb)` returns an ID for canceling
+  - `cancelAnimationFrame(id)`
+  - `scrollbarSize([recalc])` returns the scrollbar's width size in pixels
+  - `scrollTo(element, [scrollParent])`

+This repository provides a mapping of Electron versions to the Chromium version that it uses.
+
+This package is used in [Browserslist](https://github.com/ai/browserslist), so you can use e.g. `electron >= 1.4` in [Autoprefixer](https://github.com/postcss/autoprefixer), [Stylelint](https://github.com/stylelint/stylelint), [babel-preset-env](https://github.com/babel/babel-preset-env) and [eslint-plugin-compat](https://github.com/amilajack/eslint-plugin-compat).

+
+## Install
+Install using `npm install electron-to-chromium`.
+
+## Usage
+To include Electron-to-Chromium, require it:
+
+```js
+var e2c = require('electron-to-chromium');
+```
+
+### Properties
+The Electron-to-Chromium object has 4 properties to use:
+
+#### `versions`
+An object of key-value pairs with a _major_ Electron version as the key, and the corresponding major Chromium version as the value.
+
+```js
+var versions = e2c.versions;
+console.log(versions['1.4']);
+// returns "53"
+```
+
+#### `fullVersions`
+An object of key-value pairs with a Electron version as the key, and the corresponding full Chromium version as the value.
+
+```js
+var versions = e2c.fullVersions;
+console.log(versions['1.4.11']);
+// returns "53.0.2785.143"
+```
+
+#### `chromiumVersions`
+An object of key-value pairs with a _major_ Chromium version as the key, and the corresponding major Electron version as the value.
+
+```js
+var versions = e2c.chromiumVersions;
+console.log(versions['54']);
+// returns "1.4"
+```
+
+#### `fullChromiumVersions`
+An object of key-value pairs with a Chromium version as the key, and an array of the corresponding major Electron versions as the value.
+
+```js
+var versions = e2c.fullChromiumVersions;
+console.log(versions['54.0.2840.101']);
+// returns ["1.5.1", "1.5.0"]
+```
+### Functions
+
+#### `electronToChromium(query)`
+Arguments:
+* Query: string or number, required. A major or full Electron version.
+
+A function that returns the corresponding Chromium version for a given Electron function. Returns a string.
+
+If you provide it with a major Electron version, it will return a major Chromium version:
+
+```js
+var chromeVersion = e2c.electronToChromium('1.4');
+// chromeVersion is "53"
+```
+
+If you provide it with a full Electron version, it will return the full Chromium version.
+
+```js
+var chromeVersion = e2c.electronToChromium('1.4.11');
+// chromeVersion is "53.0.2785.143"
+```
+
+If a query does not match a Chromium version, it will return `undefined`.
+
+```js
+var chromeVersion = e2c.electronToChromium('9000');
+// chromeVersion is undefined
+```
+
+#### `chromiumToElectron(query)`
+Arguments:
+* Query: string or number, required. A major or full Chromium version.
+
+Returns a string with the corresponding Electron version for a given Chromium query.
+
+If you provide it with a major Chromium version, it will return a major Electron version:
+
+```js
+var electronVersion = e2c.chromiumToElectron('54');
+// electronVersion is "1.4"
+```
+
+If you provide it with a full Chrome version, it will return an array of full Electron versions.
+
+```js
+var electronVersions = e2c.chromiumToElectron('56.0.2924.87');
+// electronVersions is ["1.6.3", "1.6.2", "1.6.1", "1.6.0"]
+```
+
+If a query does not match an Electron version, it will return `undefined`.
+
+```js
+var electronVersion = e2c.chromiumToElectron('10');
+// electronVersion is undefined
+```
+
+#### `electronToBrowserList(query)` **DEPRECATED**
+Arguments:
+* Query: string or number, required. A major Electron version.
+
+_**Deprecated**: Browserlist already includes electron-to-chromium._
+
+A function that returns a [Browserslist](https://github.com/ai/browserslist) query that matches the given major Electron version. Returns a string.
+
+If you provide it with a major Electron version, it will return a Browserlist query string that matches the Chromium capabilities:
+
+```js
+var query = e2c.electronToBrowserList('1.4');
+// query is "Chrome >= 53"
+```
+
+If a query does not match a Chromium version, it will return `undefined`.
+
+```js
+var query = e2c.electronToBrowserList('9000');
+// query is undefined
+```
+
+### Importing just versions, fullVersions, chromiumVersions and fullChromiumVersions
+All lists can be imported on their own, if file size is a concern.
+
+#### `versions`
+
+```js
+var versions = require('electron-to-chromium/versions');
+```
+
+#### `fullVersions`
+
+```js
+var fullVersions = require('electron-to-chromium/full-versions');
+```
+
+#### `chromiumVersions`
+
+```js
+var chromiumVersions = require('electron-to-chromium/chromium-versions');
+```
+
+#### `fullChromiumVersions`
+
+```js
+var fullChromiumVersions = require('electron-to-chromium/full-chromium-versions');
+```
+
+## Updating
+This package will be updated with each new Electron release.
+
+To update the list, run `npm run build.js`. Requires internet access as it downloads from the canonical list of Electron versions.
+
+To verify correct behaviour, run `npm test`.
