I wonder how many companies are still using Scala.js. Scala was fun to work with, wish it was more popular these days.
Usage of Scala itself is less shiny if you look at market share. But I believe it's still growing in absolute numbers, only quite slowly.
Wow! 4 out of 20 total ain't bad!
Jocking aside the starting set (Scala developers) is already small, so it's not like either it or even less Scala.js is going to be a major player anytime soon.
