Harnessing the power of WebAssembly
summary
Compiles a C program to WebAssembly with emcc (Emscripten) and serves the generated hello.wasm via an HTML/JS loader in Visual Studio Code and Live Server, then runs the same module in Node to prove browser and backend portability. Shows near‑native performance, sandboxed security, and practical size/startup claims: wasm modules measure several megabytes and start in milliseconds startup versus container images that can be hundreds of megabytes and take seconds. Cites real users (Figma, Autodesk, Unreal) and demonstrates the C-derived logic printing “hello KCD Sri Lanka,” which works end‑to‑end.
