MDN polyfills

# Polyfills copy-pasted from MDN [![Build Status](https://travis-ci.org/msn0/mdn-polyfills.svg?branch=master)](http://travis-ci.org/msn0/mdn-polyfills) [![npm](https://img.shields.io/npm/dt/mdn-polyfills.svg)](https://www.npmjs.com/package/mdn-polyfills) ![dependencies](https://david-dm.org/msn0/mdn-polyfills.svg) [![](https://data.jsdelivr.com/v1/package/npm/mdn-polyfills/badge)](https://www.jsdelivr.com/package/npm/mdn-polyfills)

> [MDN](https://developer.mozilla.org) polyfills. A collection of side-effect ECMAScript modules. Minimized, mangled and extremely small thanks to [Rollup](https://rollupjs.org) - next-generation ES6 module bundler.

## Installation

```
npm i mdn-polyfills --save
```

## Usage

```js
import 'mdn-polyfills/POLYFILL_NAME';

// For example:

// (ES6 Modules)
import 'mdn-polyfills/Array.prototype.includes';
import 'mdn-polyfills/Object.create';

// (CommonJS)
require('mdn-polyfills/CustomEvent');
require('mdn-polyfills/String.prototype.padStart');

// and so on ...
```

Polyfills are also available over a CDN, for example

```html
<script src="https://unpkg.com/mdn-polyfills/Object.assign"></script>
<script src="https://cdn.jsdelivr.net/npm/mdn-polyfills/NodeList.prototype.forEach.js"></script>
```
