| 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.
