WebAssembly is a low-level target that applications not in JavaScript can target to run in the browser and other wasm runtimes outside the browser, including Node.js. Rust has first class support for targeting wasm.

What these technologies together offer is the opportunity write and run heavy compute tasks in worker threads inside Node.js via Rust + wasm.  Beyond the samples in the article, you can also write node-native modules with Rust using the neon[1] crate.
