I’d be tempted to push Learn Functional Programming with Elixir forward first. Now granted I’m not familiar with the content - but the outline looks promising and there are a number of excerpts available for review on the table of contents. Being in beta it’s an unfinished product but often that is the time the forum is more active, sometimes giving the opportunity to interact with fellow readers/learners.
The potential benefit that I see is that it immediately focuses on developing the “Elixir mindset” rather than exploring the many other aspects of the Elixir language and ecosystem. Recognizing and adopting that mindset should make anything that follows much easier to deal with. Following it up with Programming Elixir 1.3, one would hopefully be able to breeze through the sequential programming portion to be then exposed to the introductions of concurrent programming, OTP and macros.
As Learn Functional Programming with Elixir is a work in progress it’s probably a good idea to use it at the same time together with another book like Programming Elixir 1.3 - so that you are never waiting for the “next update”.
Now some people prefer Elixir in Action over Programming Elixir but it is bit older so there are some things to watch out for - but it is still good, especially if you prefer its focus on concurrent programming with some OTP (the update will probably be a while, though Manning does have a habit of putting a book into early access once the first three or four chapters are available).
Reading the Hex Elixir documentation in tandem with the material can be a good second perspective (going to have to get used to reading it anyway).
