Creating High-Performance Web Apps with WebAssembly

WebAssembly (WASM) is among the most disruptive technologies of 2019: It is a machine-readable program format for the web that can be executed fast, easily, and securely by browsers. For some time now, WebAssembly 1.0 has been released and is now available in all major browsers. It reduces the runtime and interpretive overhead of JavaScript, while also saving resources.

WebAssembly can already be compiled from various source languages, including C, C++ and Rust. This talk shows how WebAssembly works and how it can be used to develop a hybrid app with high-performance code written in Rust and UI code written in JavaScript.
