Who actually uses Scala.js, though? It still seems firmly in the hobbyist camp.<p>&gt; One of main strengths of Scala is that people get things done.<p>This is also true of rust, go, c++, and arguably haskell. I don&#x27;t see anything about scala that inherently makes it easier to &quot;get things done&quot;. If anything, I&#x27;ve spent a good 10% of my scala development time (over hundreds if not thousands of hours) debugging library, compiler, and documentation bugs and inconsistencies. This is not good for a language where you get things done.
