It is a good point that the specified keys(), values(), and items() return iterators rather than arrays, which makes them a little less friendly from a shimming perspective.
http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets I made a few opinionated deviations from spec in Montage’s Collections package. https://github.com/montagejs/collections I went with iterate() instead of iterator(). I feel the tide rolling over me on that one and will probably back off. keys(), values(), and items() return arrays. I didn’t even realize this was against the spec. I would have expected iterateKeys(), iterateValues(), and iterateItems() to return iterators and keys(), values(), and items() to return Array snapshots. That said, I would also expect the Iterator prototype to be pretty rich, so this would work regardless of whether keys() returns an Array or Iterator. In either case, it is straightforward to shim. map.keys().forEach(function () { }); Kris Kowal _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
