This book is a fantastic introduction to Erlang in very approachable language. It introduces the reader to both language syntax and design decisions that led to Erlang's strengths as a highly reliable programming language for realtime applications.

If you're learning Elixir right now, I can't recommend enough to also learn a bit about Erlang. The OTP and BEAM VM sit underneath both systems, and learning about what's going on under the hood helps a ton when troubleshooting production issues!
