Object.assign plugin for Babel
Babel plugin that replaces
Object.assign() with the extends helper.
Useful to reduce the need for additional polyfills or libraries when you want something that extends objects in browsers without native support.
Thanks to @sebmck for the implementation.
Instead of using
_.extend(obj1, obj2...) or
xtend(obj1, obj2...) just use
Object.assign in your code and include this plugin for Babel.
$ npm install babel babel-core babel-plugin-object-assign
Note: you need to specify
babel-core as a dependency for your project (not just
babel). This is also true if you are using a wrapper like
$ babel --plugins object-assign script.js
