I had high hope, but no, it isn't. It would only let you build your own asm.js-based VM on top of the existing JavaScript-like VM which could implement some bytecode format and interpret it. I have seen something like that already. Let me tell you, you don't want to download 20 MB for some simple web-based Tetris-clone. asm.js is useless for pretty much any modern language which relies on garbage collection. I want less indirections, not more.

  Again, these are C/C++ use-cases. That's exactly what asm.js was made for. Apart from the potential of making some of Mozilla's insane ideas like implementing a PDF reader in JavaScript easier/faster, it's applicability is pretty much limited. No one out there who is waiting for a sane language for the web will rejoice that he can now use C/C++ instead of JavaScript. > That is being worked on with the Binary Data spec: http://asmjs.org/faq.html http://asmjs.org/faq.html I'll believe it when I see it working. Most likely they will still find a way to make it next to useless, forcing people to keep writing/targeting JavaScript.

      Of course. I know his nick from the work on Rust.
