LLJS, asm.js, & Emscripten are really moving Javascript forward at incredible speed. I wonder if these projects will affect the future of the JS spec (ECMAScript Harmony + above). It's an exciting time to be a web programmer.



These projects are already affecting the spec. Here's a very small example: https://mail.mozilla.org/pipermail/es-discuss/2012-November/... which is used in asm.js and already implemented in Firefox: https://bugzilla.mozilla.org/show_bug.cgi?id=808148


Math.imul is just an ad-hoc patch to improve the performance of Emscripten. It's totally for Firefox. Is there a motivation to standardize and implement such a thing for other browser vendors? I'll star the V8 issue though...


This was added to Gecko 20.0, but it isn't part of the specs.

V8 doesn't support it: http://code.google.com/p/v8/issues/detail?id=2455
