Complete WebAssembly course: from WAT (WebAssembly Text Format) and compilation pipeline to production WASM services. Rust → WASM compilation (wasm-pack, wasm-bindgen), JavaScript interop (WebAssembly.instantiate, SharedArrayBuffer), WASI (WebAssembly System Interface) — filesystem, sockets, HTTP, Component Model, Wasmtime/WasmEdge runtime, WASM on the edge (Cloudflare Workers, Fastly Compute@Edge), WASM plugins (Envoy, VS Code, database UDFs), Docker + WASM integration, performance comparison with native code and containers.
