LYAH was my first taste of functional programming. Before that I only had 2-3 years of experience using PHP and Ruby. I read this book and quickly fell in love with FP and category theory, for the first time really started to enjoy programming to the fullest. This book is also the reason I was able to land a job as an Erlang developer, and teach a little bit of Haskell to others. Now, 5 years later, I continue my studies with languages such as Emacs Lisp, Guile, Clojure, Elixir, Elm, Hy.

I know this book isn't really popular (reading these comments) but to me it holds a lot of emotional value and I felt obligated to share my experience. I'll always be grateful for what this book taught me, and thankful to Miran for writing it.

For me too. I had some experience of FP and was also a PHP programmer. It's one of the funniest programming books I've ever read, references to Avril Lavigne amongst category theory appeals to my sort, but clearly it's not a book for everyone.

So I found it fun to learn and the concept of Applicative Functors in between Monoids and Monads has stuck. As well as the examples of monads, such as walking on a tight rope with birds landing either side.

I'm still not doing pure FP and so I forget much of the content, but its a pleasure to pick up and re-read.

What are you building with Erlang? If you don't mind sharing. I always love hearing about it being used in production... Usually it's used in interesting ways. Unfortunately not to many jobs available (not that I've tried very hard to find one).

We use Erlang to build Kazoo (https://github.com/2600hz/kazoo). In production since 2011, deployed around the world in various clusters.
