OdinMonkey and Asm.js arrive in Firefox Nightly
Currently though, it is early days for Asm.js and OdinMonkey. Developers wanting to test them will need to be running Windows or Linux with x86/x64; Mac OS X and Firefox on ARM builds are "almost done" but not here yet. The spec and implementation will be enhanced over the coming months too and the flag controlling OdinMonkey's operations (
about:config), although currently enabled, will be disabled when this edition of Firefox goes into beta and should be reenabled on final release. Aspiring developers will also want to get Emscripten to compile their C/C++ code; in the future, the Asm.js developers hope to offer another language such as a derivative of LLJS. There are still many issues with Asm.js and OdinMonkey to be overcome though, from a lack of analogues for C++ backend optimisations to a high cost between moving between non-Asm.js code and Asm.js code.
