/**
  * 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`](https://mdn.io/Object/assign).
  *
  * @since 5.5.0
  * @category Object
  * @param object The destination object.
  * @param sources The source objects.
  * @returns Returns `object`.
  * @see [[assignIn]]
  * @example
  *
  * ```js
  * 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 }
  * ```
