I'm learning Elixir at this moment. As Elixir is built upon Erlang, I found "Programming Erlang, second edition" by Joe Armstrong to be a gentler introduction.

I'm learning Elixir at this moment. As Elixir is built upon Erlang, I found "Programming Erlang, second edition" by Joe Armstrong to be a gentler introduction. After 20+ years of OO (and my mental models built upon C and assembly), functional programming and Erlang's model built upon immutable variables, pattern matching broke my brain for a few days. I just didn't get it. However, I didn't stop. I am now bouncing between both books and it's beginning to sink in.
