/**
* 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.
*
* @since 0.1.0
* @category Lang
* @param {*} value The value to clone.
* @returns {*} Returns the cloned value.
* @see cloneDeep
* @example
*
* const objects = [{ 'a': 1 }, { 'b': 2 }];
*
* const shallow = clone(objects);
* console.log(shallow[0] === objects[0]);
* // => true
