Running rust in wasm works really well. I feel like I'm the world's biggest cheerleader for it, but I was just amazed at how well it works. The one annoying thing is using web APIs through rust - you can do it with web-sys and js-sys, but it's rarely as ergonomic as it is in javascript. I usually end up writing wrapper libraries that make it easy, sometimes even easier than javascript (e.g. in rust I can use weblocks with RAII)

It does work well logically but performance is pretty bad. I had a nontrivial Rust project running on Cloudflare Workers, and CPU time very often clocked 10-60ms per request. This is >50x what the equivalent JS worker probably would've clocked. And in that environment you pay for CPU time...

The rust-js layer can be slow. But the actual rust code is much faster than the equivalent JS in my experience. My project would not be technically possible with javascript levels of performance
