Set.prototype.entries()

The entries() method of Set instances returns a new set iterator object that contains [value, value] for each element in this set, in insertion order. For Set objects there is no key like in Map objects. However, to keep the API similar to the Map object, each entry has the same value for its key and value here, so that an array [value, value] is returned.
