I'm not sure what you think is happening, but there's nothing that defeats a polyfill in Map or Set. As Arv says, it's allowed to pass an iterable in their constructor, but you can ignore that if you want. The .keys/values/entries() methods return iterators, but you can easily polyfill that if you'd like. Both of them have .forEach() methods which just take a callback, exactly like Array#forEach(). ~TJ _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
