* 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]). |

* @param {*} value The value to clone. |
|
* @param {Function} [customizer] The function to customize cloning. |
|
* @returns {*} Returns the cloned value. |

|
* function customizer(value) { |
