			# object-assign [![Build Status](https://travis-ci.org/sindresorhus/object-assign.svg?branch=master)](https://travis-ci.org/sindresorhus/object-assign)

			> ES2015 [`Object.assign()`](http://www.2ality.com/2014/01/object-assign.html) [ponyfill](https://ponyfill.com)


			## Use the built-in

			Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
			support `Object.assign()` :tada:. If you target only those environments, then by all
			means, use `Object.assign()` instead of this package.


			## Install

			```
			$ npm install --save object-assign
			```


			## Usage

			```js
			const objectAssign = require('object-assign');

			objectAssign({foo: 0}, {bar: 1});
			//=> {foo: 0, bar: 1}

			// multiple sources
			objectAssign({foo: 0}, {bar: 1}, {baz: 2});
			//=> {foo: 0, bar: 1, baz: 2}

			// overwrites equal keys
			objectAssign({foo: 0}, {foo: 1}, {foo: 2});
			//=> {foo: 2}

			// ignores null and undefined sources
			objectAssign({foo: 0}, null, {bar: 1}, undefined);
			//=> {foo: 0, bar: 1}
			```


			## API

			### objectAssign(target, [source, ...])

			Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.
