I had a look at both WebAssembly and Rust a few months back, in the hope they could help me write some nice, fast graphics filters that I could then compile out and use via Wasm in a 2d canvas. Entirely do-able, but beyond my limits of understanding and patience.

Since then, I've stuck with what I know (Javascript) and branched instead into consuming Wasm written by others (in whatever language) on the frontend for my own experiments - for instance Rapier[1] which is a physics engine written in Rust, and some of the MediaPipe ML models[2].
