asm.js

asm.js is a low-level, highly optimized subset of JavaScript designed to enable near-native performance in web browsers. It acts as a target format for compilers, allowing code written in languages like C or C++ to be translated into a version that runs efficiently in the browser. By providing a predictable, typed structure, asm.js helps browsers execute complex computations faster than regular JavaScript, making it suitable for performance-critical applications like games or simulations directly on the web without needing additional plugins.
