Typed Objects polyfill lives here: https://github.com/dherman/structs.js Dave and I work on it, current status is pretty close to strawman minus handles and cursors (which are a bit controversial at this point and as far as I understand are not is Firefox implementation). The polyfill includes a bunch of tests; I haven't yet run it on Mozilla tests - will get to it soon hopefully.
I welcome and will be happy to review polyfill patches. Dmitry On Sun, Nov 17, 2013 at 2:04 PM, Till Schneidereit < [email protected]> wrote: > On Sun, Nov 17, 2013 at 10:23 AM, K.
