We use Scala as well and are very happy with it. We also have a lot of TS, and at this point we are tempted to just switch to using ScalaJS on the frontend as well because of how much better the language is to use. It feels like Scala 3 fixed a lot of issues people had with the language. The IDE tooling isn’t the best, but even then it feels like the IDE tooling for TS breaks all the time once the project is large enough.

I did that and highly recommend it, at least for new projects - not sure that it's worth the effort of porting an existing project, but ScalaJS just works and I found far fewer rough edges than I expected.
