Very good introduction
5 stars
Very interesting, beginner-friendly guide to functional programming and Elixir. What is functional programming, why is it worth learning, and how does Elixir behave.
My main criticism would be the pacing. Almost all of the book is paced well; concepts are not laboured (there's a distinct lack of 'five pages explaining the difference between float and integer'), and it all feels good. Except for one chapter - the 'main' chapter where you build an application - it feels like the pacing is doubled or even tripled. Maybe that is just me being a novice, but I felt that chapter could have been paced as two or three chapters and felt better for me.
But I'd still recommend it - it's a really good book. I think I will probably just need to review that one chapter a few more times before it really sinks in.
