Object.assign()ponyfill
Use the built-in
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 object-assign
Usage
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.
