	/**
	* 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
