Iterator

An Iterator object is an object that conforms to the iterator protocol by providing a next() method that returns an iterator result object. The Iterator.prototype object is a hidden global object that all built-in iterators inherit from. It provides a @@iterator method that returns the iterator object itself, making the iterator also iterable.
