Getting things done with Elixir - tips?

Try to develop something very simple, like an Encryptor.

Give a read to this tutorial which teaches you, how to develop an Encryptor in Ruby. Then do the same in Elixir. That’s how I practice Elxir.
Try to use IEx helper h() as much as possible.

BTW, what do you wanna use Elixir for, primarily?
