You nailed it. I work with Ruby, TypeScript (React, Node) and Elixir.

While Elixir has more than enough uses and I love it dearly, nothing comes close to the productivity and expressiveness of Ruby (+ Rails).

I have very high hopes for JS/TS. Using a single isomorphic language for web development must have some benefits, but I'm afraid it's not there yet.
