(If you're asking about what flavor of Javascript I use) I just use plain JS for the bits of JS I need, but nothing I have been working on needs a heavy front-end.

There's not really an Elixir equivalent of Clojurescript to Clojure (there is an Elixirscript, but it's a work in progress and I'm curious whether it can ever capture the nice experience of using the Erlang VM). I've seen interest in the Elixir community in Elm and Bucklescript(OCaml) and other compiled-to-js languages, but I think a lot of people just use JS.
