ASM.js has nothing to do with performance. It's about abstracting away the utter pile of shit that is JavaScript so that we can start using the languages of real men on the web. There have been plenty of works done in this area already. See WebSharper, Script#... just two of the many available in the .NET ecosystem. ASM.js is about formalising a known-good subset of JS that can be guaranteed to be compatible across browsers and therefore prime territory for building compilers on top of. JS is nothing more than an intermediate language; it is similar to MSIL, JVM Bytecode, ASM. The only difference is that it happens to have a slightly C-style syntax. This is merely a coincidence and does not change the fact that is still an intermediate language designed for the web. It is utterly crazy the world has persisted writing code in it for so long. It is the modern web day equivalent of writing code in Assembly language.
