I also recommend to read Metaprogramming Elixir by Chris McCord (the person who build the Phoenix framework) https://pragprog.com/book/cmelixir/metaprogramming-elixir. By reading this book you get a great understanding about how a framework as Phoenix works deeper down.

When I started learning Rails I took the wrong approach in my opinion. It read a small bit about Ruby and started with a book about Rails. I got a bit confused about which part of the code was Ruby specific and which was Rails (since Rails adds some extra functionality to the default Ruby). So you should learn Elixir first ;)!

In my opinion if you are in part 3 of the Programming Elixir book then I think you should just finish it first. If you’re not in a hurry to learn Phoenix then I’d also recommend to work on a small project in Elixir first before jumping into Phoenix. Phoenix really is a beast on its own and a good grasp of Elixir can really help you understand the framework.

Thanks @sashaafm Though it’s tempting to grab the new book, I will heed your advice and complete reading it. I have been sticking to the chapter exercises so far. So, I need to pick something(s) to create using Elixir to get a better grip. Time to hunt some project ideas.
