WebAssembly (WASM) is binary format that runs at near native speed. The technology is supported by all major browsers, but can also be used outside of the browser. Today you can cross-compile Rust, C and C++ code to WASM. This allows you to pick the best parts of each language environment and use them in a single project.
In this talk Auke will give an introduction into WASM. He will also demonstrate how you can create a WASM binary from Rust code and use this WASM binary both client side with Javascript and server side together Python.
