Object.assign()
ponyfill
Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
support Object.assign()
๐. If you target only those environments, then by all
means, use Object.assign()
instead of this package.
npm install object-assign
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}
Assigns enumerable own properties of source
objects to the target
object and returns the target
object. Additional source
objects will overwrite previous ones.
