" summary

Explains WebAssembly as a browser bytecode you compile to so you can run non-JavaScript code, demonstrates building a tiny fizzbuzz module in WebAssembly Text Format (the .wat compiles to a 72‑byte .wasm) and then reimplements it with Rust (initial wasm ~1.7 MB, reduced later), shows loading with fetch + WebAssembly.instantiate/streaming, uses wabt (wat2wasm), VS Code plugin and a Python dev server, proves functions and memory-backed strings work but DOM access still requires JavaScript.
