      7  * This method is like `_.clone` except that it accepts `customizer` which
      8  * is invoked to produce the cloned value. If `customizer` returns `undefined`,
      9  * cloning is handled by the method instead. The `customizer` is invoked with
     10  * up to four arguments; (value [, index|key, object, stack]).
