Yep. Where I notice it the most is frontend stuff. We've been using a WebAssembly framework, particularly Leptos, where you get to write HTML+CSS+Rust.

And normally, a colleague and I despise frontend, i.e. JavaScript. Like, it's kind of cool, because you get a visual result, but the crimes against humanity you have to commit in terms of code readability were very visible to us.

And yeah, Leptos and Rust are a lot better in that regard, which boosts productivity. Particularly when a backend request fails, you get a Result, which you can pass as one value to the display code and just display either the data or an error. That's huge, because you make a lot of backend requests.

One downside in productivity and fun is that there obviously aren't yet as many component libraries, so if you want a toast notification, you might need to implement that yourself.

But still, we almost had to seriously ask that colleague to pause dishing out frontend features, because he was enjoying it so much.
