WebAssembly for Web Developers

on YouTube ↗40m

" summary

WebAssembly compiles existing C/C++ and Rust libraries into browser modules: MozJPEG compiled to WebAssembly powers Squoosh, replacing the browser JPEG encoder to produce smaller files and expose advanced options; image rotate benchmarks show JavaScript timings ranging 400 ms vs 8 s variance while multiple wasm implementations cluster around ~500 ms, giving far more predictable performance. Tooling notes: emscripten offers POSIX emulation (watch bundle size), wasm-pack for Rust, AssemblyScript TypeScript→Wasm exists, and platform features landing or planned include Chrome 74 ships threads, SIMD, reference types and web IDL bindings.
