Meet Your Future - WebAssembly
summary
WebAssembly is a simple stack‑based bytecode with four value types, linear memory and no GC today, and it runs in runtimes like wasmer and Wasmtime. Practical demos compile text .wat to .wasm and run: add.wasm -> add(2,3)=5 via wasmer and a browser demo shows 2+2=4. A Doomfire demo imports Math.random and uses 5 pages (64 KB each) to update a canvas each frame. A Rust example uses wasm-bindgen to produce an npm site that alerts "hellocraft.com". Use cases: games/Unity, AutoCAD C++ ports, FaaS (Fastly Compute@Edge, Cloudflare Workers), Ethereum contracts, IoT and Kubernetes integration; WASI provides capability‑based OS access.
