  /**
   * Creates a clone of `value`. If `isDeep` is `true` nested objects are cloned,
   * otherwise they are assigned by reference. If `customizer` is provided it is
   * invoked to produce the cloned values. If `customizer` returns `undefined`
   * cloning is handled by the method instead. The `customizer` is bound to
   * `thisArg` and invoked with two argument; (value [, index|key, object]).
   *
   * **Note:** This method is loosely based on the structured clone algorithm.
   * The enumerable properties of `arguments` objects and objects created by
   * constructors other than `Object` are cloned to plain `Object` objects. An
   * empty object is returned for uncloneable values such as functions, DOM nodes,
   * Maps, Sets, and WeakMaps. See the [HTML5 specification](http://www.w3.org/TR/html5/infrastructure.html#internal-structured-cloning-algorithm)
   * for more details.
