" summary

Company migrates a client-side CDN load balancer from JavaScript to C++ compiled with Emscripten and deploys the WASM build to production, keeping one codebase for web, iOS, and Android. Design uses an actor/task scheduler so small tasks run on the browser event loop and on native threads, avoiding data races. Highlights: Emscripten flags: -Os, --profiling, --memory-profiler, --closure 1, Syncify doubles binary size and adds overhead, single-threaded browser constraints and web worker/SharedArrayBuffer limits.
