asm.js

Being strict by nature means asm.js can run in older browsers, even if not at maximum capabilities.

asm.js is basically a JavaScript compiler, taking syntax written in asm.js specific syntax and porting it back to JavaScript.

The entire system was inspired and modeled after C/C++ virtual machines, for faster compilation times and fewer runtime errors.

When development finished and when reaching a stable build, asm.js will allow developers to write more complicated JS code structure, while also benefiting from faster compilation speeds.

asm.js works with both AoT (Ahead of Time) and JiT (Just in Time) compilers.

Requirements:

• Node.js 0.8.2 or higher

Limitations:

• Still under development.
