/** | |
* This method is like `_.update` except that it accepts `customizer` which is | |
* invoked to produce the objects of `path`. If `customizer` returns `undefined` | |
* path creation is handled by the method instead. The `customizer` is invoked | |
* with three arguments: (nsValue, key, nsObject). | |
* | |
* **Note:** This method mutates `object`. | |

* @param {Object} object The object to modify. | |
* @param {Array|string} path The path of the property to set. | |
* @param {Function} updater The function to produce the updated value. | |
* @param {Function} [customizer] The function to customize assigned values. | |
* @returns {Object} Returns `object`. | |
* @example | |

* var object = {}; | |
* | |
* _.updateWith(object, '[0][1]', _.constant('a'), Object); | |
* // => { '0': { '1': 'a' } } | |
