/**

* Assigns own enumerable 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`](https://mdn.io/Object/assign).

*

* @static

* @memberOf _

* @category Object

* @param {Object} object The destination object.

* @param {...Object} [sources] The source objects.

* @returns {Object} Returns `object`.

* @example

*

* function Foo() {

* this.c = 3;

* }

*

* function Bar() {

* this.e = 5;

* }

*

* Foo.prototype.d = 4;

* Bar.prototype.f = 6;

*

* _.assign({ 'a': 1 }, new Foo, new Bar);

* // => { 'a': 1, 'c': 3, 'e': 5 }
