Scala isn’t dead. I’m job hunting right now, and seeing plenty of Scala jobs. Not as many as Node+TS+React, but what do you expect?
Scala.js has excellent front-end frameworks like Slinky React [1], Laminar [2] and Scala has industry-leading concurrency libraries like ZIO [3]. I've yet to find anything that comes close for end to end web apps.

Scala isn't dead. It went to play between the stars with Pearl and Ruby.
