|  | # ES6 Object.assign() | 
|  |  | 
|  | ECMAScript 2015 (ES2015/ES6) [Object.assign()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign) polyfill and [ponyfill](https://ponyfill.com) for ECMAScript 5 environments. | 
|  |  | 
|  | The main definition of this package has been copied from the polyfill defined in the [Mozilla Developer Network](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/assign). | 
|  |  | 
|  | ## Installation | 
|  |  | 
|  | ### NPM | 
|  |  | 
|  | ```bash | 
|  | npm install es6-object-assign | 
|  | ``` | 
|  |  | 
|  | ### Manual download and import | 
|  |  | 
|  | The package is also available as a UMD module (compatible with AMD, CommonJS and exposing a global variable `ObjectAssign`) in `dist/object-assign.js` and `dist/object-assign.min.js` (833 bytes minified and gzipped). | 
|  |  | 
|  | The versions with automatic polyfilling are `dist/object-assign-auto.js` and `dist/object-assign-auto.min.js`. | 
|  |  | 
|  | ## Usage | 
|  |  | 
|  | **CommonJS**: | 
|  |  | 
|  | ```javascript | 
|  | // Polyfill, modifying the global Object | 
|  | require('es6-object-assign').polyfill(); | 
|  | var obj = Object.assign({}, { foo: 'bar' }); | 
|  |  | 
|  | // Same version with automatic polyfilling | 
|  | require('es6-object-assign/auto'); | 
|  | var obj = Object.assign({}, { foo: 'bar' }); | 
|  |  | 
|  | // Or ponyfill, using a reference to the function without modifying globals | 
|  | var assign = require('es6-object-assign').assign; | 
|  | var obj = assign({}, { foo: 'bar' }); | 
|  | ``` | 
|  |  | 
|  | **Globals**: | 
|  |  | 
|  | Manual polyfill: | 
|  |  | 
|  | ```html | 
|  | <script src="<your-libs-directory>/object-assign.min.js"></script> | 
|  | <script> | 
|  | // Polyfill, modifying the global Object | 
|  | window.ObjectAssign.polyfill(); | 
|  | var obj = Object.assign({}, { foo: 'bar' }); | 
|  | </script> | 
|  | ``` | 
|  |  | 
|  | Automatic polyfill: | 
|  |  | 
|  | ```html | 
|  | <script src="<your-libs-directory>/object-assign-auto.min.js"></script> | 
|  | <script> | 
|  | var obj = Object.assign({}, { foo: 'bar' }); | 
|  | </script> | 
|  | ``` | 
|  |  | 
|  | Ponyfill, without modifying globals: | 
|  |  | 
|  | ```html | 
|  | <script src="<your-libs-directory>/object-assign.min.js"></script> | 
|  | <script> | 
|  | var assign = window.ObjectAssign.assign; | 
|  | var obj = assign({}, { foo: 'bar' }); | 
|  | </script> | 
|  | ``` |
