WebAssembly fulfills the long-awaited promise of web technologies: fast code, type-safe at compile time, execution in the browser, on embedded devices, or anywhere else. Rust delivers the power of C in a language that strictly enforces type safety. Combine both languages and you can write for the web like never before! In this demo-heavy talk Kevin will take us on a journey from the basics of WebAssembly to using WebAssembly to integrate with JavaScript, build complete websites, and even host and interpret in Rust apps. He'll even show hot-swapping WebAssembly modules to control LEDs on a Raspberry Pi. Follow us on Twitter: https://twitter.com/rustlatamconf
