What is WebAssembly (Wasm)?

A binary instruction format that enables near-native performance execution of code in web browsers alongside JavaScript.

WebAssembly runs compiled code (from C, C++, Rust, Go) in browsers at near-native speed. Unlike JavaScript, Wasm is a low-level binary format that browsers execute efficiently. It complements JavaScript rather than replacing it.

Use cases include gaming engines, image/video processing, CAD applications, scientific simulations, and running existing C/C++ libraries in browsers. WASI extends Wasm beyond browsers to server-side and edge computing.
