Bringing the power of C++ to the web

on YouTube ↗39m

" summary

C++ compiles to WebAssembly and runs in browsers using Emscripten with a small demo add function and a threaded example that actually interleaves output when run locally. WebAssembly performance sits between native and asmjs but threads + SIMD promise order-of-magnitude gains; threads remain experimental in many browsers. Tooling costs are real: generated glue can be ~260 KB, enabling exceptions adds ~40% size, and debugging relies on JavaScript source maps. Streaming compilation reduces startup latency and is supported via instantiateStreaming.
