Mozilla’s Asm.js Gets Another Step Closer To Native Performance

Mozilla’s asm.js is a strict subset of JavaScript that Firefox can run significantly faster than regular JavaScript code. Thanks to the so-called OdinMonkey module for Firefox’s built-in JavaScript engine, asm.js code was running at about 2x native speed in March and this week, the organization announced that it’s now running most benchmarks at just 1.5x slower than native or better.

While Google is betting on Native Client to allow web apps to execute native compiled code in the browser, Mozilla is betting on its ability to run JavaScript at near-native speeds, too. While they approach this problem from very different angles, both Google, through Native Client, and Mozilla, through its Emscripten LLVM-to-JavaScript compiler, allow developers to write their code in C or C
