/**
* This method is like `set` except that it accepts `updater` to produce the
* value to set. Use `updateWith` to customize `path` creation. The `updater`
* is invoked with one argument: (value).
*
* **Note:** This method mutates `object`.
*
* @since 4.6.0
* @category 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.
* @returns {Object } Returns `object`.
* @example
*
* const object = { 'a': [{ 'b': { 'c': 3 } }] }
*
* update(object, 'a[0].b.c', n => n * n)
* console.log(object.a[0].b.c)
* // => 9
*
* update(object, 'x[0].y.z', n => n ? n + 1 : 0)
* console.log(object.x[0].y.z)
* // => 0
