Polyfills copy-pasted from MDN

MDN polyfills. A collection of side-effect ECMAScript modules. Minimized, mangled and extremely small thanks to Rollup - next-generation ES6 module bundler.

Installation

npm i mdn-polyfills --save

Usage

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

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