JavaScript to Rust and Back Again: A wasm-bindgen Tale

Recently we’ve seen how WebAssembly is incredibly fast to compile, speeding up JS libraries, and generating even smaller binaries. We’ve even got a high-level plan for better interoperability between the Rust and JavaScript communities, as well as other web programming languages. The goal of wasm-bindgen is to provide a bridge between the types of JavaScript and Rust. It allows JS to call a Rust API with a string, or a Rust function to catch a JS exception. wasm-bindgen erases the impedance mismatch between WebAssembly and JavaScript, ensuring that JavaScript can invoke WebAssembly functions efficiently and without boilerplate, and that WebAssembly can do the same with JavaScript functions.
