We&#x27;ve started using Elixir in our Erlang application and it&#x27;s been a pleasure to work with. Everyone in my office agrees they would&#x27;ve loved to have this when they started with Erlang.

I&#x27;ve been keeping an eye on Elixir for a while, waiting for some spare time. What are reasons not to use it in favour of Erlang?

Has anyone used Elixir in production yet?
