Скачать или смотреть WASM Rust Tutorial with Rust: Supercharge Your Web Apps with Rust & WebAssembly (Step by Step)

In this wasm rust tutorial, you’ll learn how to build blazing-fast web applications using Rust and WebAssembly (WASM). You’ll start from installing rustup and wasm-pack, walk through hello_wasm setup, and see Rust functions called directly from JavaScript in the browser. Discover how wasm-bindgen bridges UTF‑8/UTF‑16, compare performance trade-offs, and learn best practices for real-world Rust + WebAssembly integration. Very basic WebAssembly demo to start with!

Whether you're a web developer, a Rust beginner, or exploring WebAssembly for performance, this video walks you through everything you need to know.
