• Branching constructs (case, cond, if) are explored in chapter 3.
• try is briefly mentioned but not explored in details.
• File I/O is mostly not discussed. The example which is developed throughout the book uses File.read and File.write, and there’s a brief example of File.stream! in chapter 3, and that’s all.

Getting Started and Introduction to Mix are definitely worth your time.

Hexdocs quality depends on the package providers - and as valuable and high quality the hexdocs for Phoenix and Ecto are, I feel that going through Programming Phoenix 1.4 and Programming Ecto first helps you to get more out the hexdocs (and makes them easier to understand).

Elixir in Action 2e is an excellent guide to learning how to develop Elixir applications (the Elixir/BEAM way). That being said some people may benefit from some additional help from Learn Functional Programming in Elixir to get more used to the functional way of doing things.

Also, when is the second edition of EiA coming out? Some stores says September 30th but Amazon says November 6th.

These topics would be covered in any introductory elixir book or guide, I think. You might as well try

Quoting the book from @sasajuric , notable changes between 1st and 2nd edition are:

• HashDict -> Map
• new Supervisor child specifications
• Registry
• DynamicSupervisor
• exrm -> distillery
• intro to testing

Further to what has been said already, I highly recommend the book It really helped me understand what is going on with GenServers and Supervisors since you build them from scratch in the book. It’s an excellent book all round.

I wrote a small review about the first edition here
