WebAssembly (WASM) is a binary instruction format that runs in browsers at near-native speed. It enables languages like C, C++, Rust, and Go to compile to a format that runs in the browser alongside JavaScript. Use cases: image/video processing, games, CAD tools, and any compute-heavy task that would be too slow in JavaScript. WASM runs in all modern browsers and is sandboxed for security.
