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