* Creates a shallow clone of `value`.

|

|
|
* **Note:** This method is loosely based on the
|
||
|
|
* [structured clone algorithm](https://mdn.io/Structured_clone_algorithm)
|
||
|
|
* and supports cloning arrays, array buffers, booleans, date objects, maps,
|
||
|
|
* 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.
