" summary

Emscripten compiles LLVM bitcode from C/C++ into JavaScript and shows full, working ports: Bullet physics engine running in canvas, SQLite in the browser, Python/Ruby/Lua runtimes and espeak synthesis, not just toy examples. Claims: automatic whole-library ports, a bindings generator that exposes C++ headers to JS, and typical speed at roughly 2–5× slower than native with real-world variability. Caveats: some source tweaks or manual destroys are required, startup and engine bugs affect performance, and I/O maps to synchronous XHR by default.
