WebAssembly: Binary in Plain English
summary
WebAssembly lets compiled C/C++/Rust (and AssemblyScript) run in the browser for real performance gains by delivering a binary format with streaming compilation and a small static type set (four numeric types). Tooling examples: Emscripten, Rust’s compiler + wasm-bindgen, and AssemblyScript; practical deployments include Facebook image processing with libjpeg, Wikipedia audio with opus, OpenCV in-browser, Squoosh (C++/Rust/AssemblyScript), AutoCAD and Google Earth ports; over 600+ modules on npm and ~87% browser support.
