Lodash

assign

Object
since 0.10.0

Arguments

  • Object The destination object.
  • ...Object The source objects.

Returns

Object `object`.

Assigns own enumerable string keyed properties of source objects to the destination object. Source objects are applied from left to right. Subsequent sources overwrite property assignments of previous sources.

Note: This method mutates object and is loosely based on Object.assign.

Example of Lodash _.assign

function Foo() {
  this.a = 1;
}

function Bar() {
  this.c = 3;
}

Foo.prototype.b = 2;
Bar.prototype.d = 4;

_.assign({ 'a': 0 }, new Foo, new Bar);
// => { 'a': 1, 'c': 3 }
