This is true if you're agnostic to or prefer dynamic typing. If you're using Node, that's probably true, but at the high level I tend to think of Haskell, OCaml, F#, and Scala as the comparisons.

As someone who likes neither dynamic typing or Ruby's syntax, I do agree that Elixir looks very cool, and have considered it for jobs that favor development speed over compile-time correctness.
