WebAssembly: Taking Your C++ and Going Places
summary
Claims that WebAssembly runs C++ on the web about 4.2× faster than JavaScript and compiles with Emscripten (emcc); demos show a logger that writes to IndexedDB, posts logs to a server, and runs on a separate pthread-based worker using shared array buffer, so threading actually works when browser flags allow it. Tooling includes DWARF for DWARF source-level debugging in Chrome, default linear memory 16 MB (browser caps ~4 GB Chrome, ~2 GB Firefox/Safari), and the repo contains Docker/setup and working examples.
