|  |  * **Note:** This method is loosely based on the | ||
|  |  * [structured clone algorithm](https://mdn.io/Structured_clone_algorithm)
 | ||

|  |  * numbers, `Object` objects, regexes, sets, strings, symbols, and typed | ||
|  |  * arrays. The own enumerable properties of `arguments` objects are cloned | ||
|  |  * as plain objects. An empty object is returned for uncloneable values such | ||
|  |  * as error objects, functions, DOM nodes, and WeakMaps. | ||
