You see , Elixir itself is a functional language with the power of Erlang which is a so damn power-full language to create telephony based enterprise solutions . Even Whats App and Facebook use Erlang for handling millions of connections .
I see Elixir really promising in new era. it has power of erlang and simplicity of ruby like syntax.
And about phoenix I would say it is made for you to create solutions that really does matter and really big. For api driven and new technology methodologies that can help you grow and smile at same time.
I am thinking of writing my experiences with elixir and phoenix soon . Take care ...
