ES2015 Object.assign()ponyfill

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

npm install object-assign

constobjectAssign=require('object-assign');objectAssign({foo: 0},{bar: 1});//=> {foo: 0, bar: 1}// multiple sourcesobjectAssign({foo: 0},{bar: 1},{baz: 2});//=> {foo: 0, bar: 1, baz: 2}// overwrites equal keysobjectAssign({foo: 0},{foo: 1},{foo: 2});//=> {foo: 2}// ignores null and undefined sourcesobjectAssign({foo: 0},null,{bar: 1},undefined);//=> {foo: 0, bar: 1}

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