this is really easy to fix via code but I would rather propose an Array#compact() or Array#dense() method rather than changing everything else (included shims/polyfills)
I really don't remember when it happened last time that I had to deal with such kind of Arrays ... and this made already every polyfill slower with the `index in array` check per each element in the loop: edge case, a bit too much, imho, not worth it to include now in every method otherwise we gonna have all native Array wrappers meanwhile that browsers will catch up, I can bet that On Mon, Nov 12, 2012 at 3:24 PM, Jason Orendorff <jason.orendo...@gmail.com>wrote: > On Mon, Nov 12, 2012 at 4:39 PM, Allen Wirfs-Brock > <al...@wirfs-brock.com>wrote: > >> So the question on the floor: is there any interest in having this >> variation of array iteration in ES6? >> > > No. Why complicate the API with a feature just for people who use sparse > arrays on purpose?
