If you target only those environments, then by all means, use `Object.assign()` instead of this package. ## Install ```sh npm install object-assign ``` ## Usage ```js 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. ## Resources - [ES2015 spec - Object.assign](https://www.ecma-international.org/ecma-262/6.0/#sec-object.assign)
