/**
|
|
* 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' } }
