Learn You a Haskell for Great Good! A Beginner’s Guide

Youll start with the kid stuff: basic syntax, recursion, types and type classes. Then once youve got the basics down, the real black belt master-class begins: youll learn to use applicative functors, monads, zippers, and all the other mythical Haskell constructs youve only read about in storybooks.
As you work your way through the authors imaginative (and occasionally insane) examples, youll learn to:
Laugh in the face of side effects as you wield purely functional programming techniques
Use the magic of Haskells «laziness» to play with infinite sets of data
Organize your programs by creating your own types, type classes, and modules
Use Haskells elegant input/output system to share the genius of your programs with the outside world
Short of eating the authors brain, you will not find a better way to learn this powerful language than reading Learn You a Haskell for Great Good!
