Presentation: Rust, WebAssembly, and Javascript Make Three: An FFI Story

WebAssembly is an exciting new compilation target for the web platform and beyond. While many herald its arrival as the death of JavaScript- the story on the ground is quite different. In this talk, we‘ll tour the Rust and WebAssembly toolchain and the fascinating and challenging technical work involved in creating a developer friendly experience designed to grow adoption of WebAssembly- particularly amongst JavaScript developers. Notably, we‘ll take a deep dive into the foundational tool, `wasm-bindgen`, and how (and why!) we‘ve taught Rust compiled WebAssembly to interact seamlessly with JavaScript APIs and toolchains.
