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.
Install
$ npm install --save object-assign
Usage
const objectAssign = ; ;//=> {foo: 0, bar: 1} // multiple sources;//=> {foo: 0, bar: 1, baz: 2} // overwrites equal keys;//=> {foo: 2} // ignores null and undefined sources;//=> {foo: 0, bar: 1}API
