      9  * **Note:** This method is loosely based on the
     10  * [structured clone algorithm](https://mdn.io/Structured_clone_algorithm)
     11  * and supports cloning arrays, array buffers, booleans, date objects, maps,
     12  * numbers, `Object` objects, regexes, sets, strings, symbols, and typed
     13  * arrays. The own enumerable properties of `arguments` objects are cloned
     14  * as plain objects. An empty object is returned for uncloneable values such
     15  * as error objects, functions, DOM nodes, and WeakMaps.
