15 * Assigns own enumerable string keyed properties of source objects to the
16 * destination object. Source objects are applied from left to right.
17 * Subsequent sources overwrite property assignments of previous sources.
18 *
19 * **Note:** This method mutates `object` and is loosely based on
20 * [`Object.assign`](https://mdn.io/Object/assign).

25 * @category Object
26 * @param {Object} object The destination object.
27 * @param {...Object} [sources] The source objects.
28 * @returns {Object} Returns `object`.
29 * @see _.assignIn
30 * @example
31 *
32 * function Foo() {
33 * this.a = 1;
34 * }
35 *
36 * function Bar() {
37 * this.c = 3;
38 * }

40 * Foo.prototype.b = 2;
41 * Bar.prototype.d = 4;
42 *
43 * _.assign({ 'a': 0 }, new Foo, new Bar);
44 * // => { 'a': 1, 'c': 3 }
