Haskell is really a language very worth knowing. It does many things so different than most other languages which I really enjoy.

I’d like to use this post to mention a few really good resources for learning Haskell:

Learn you a Haskell

Learn you a Haskell is a very fun and entertaining tutorial for Haskell very much in the spirit of Why’s poignant guide to Ruby.

It isn’t finished yet, but it’s really good to start with. (Via Wadler’s Blog)

Real World Haskell

Real World Haskell is a upcoming book I really look forward to. It is freely available on its website, so check it out.

Wikibook

There is also a good collection of Haskell topics on Wikibooks – Programming/Haskell

Wikibook is more interesting if you already know a bit of Haskell and would like to understand it more in depth.

Others

I liked Yet another Haskell Tutorial very much, this aims at people with a bit of background, though.

Another more recent book on Haskell is Programming in Haskell which is nice, but also quite basic IMO.

Of course there is always the Gentle introduction to Haskell

Enjoy.

Haskell is doomed to succeed. —Sir Tony Hoare

Haskell is a non-strict, or lazy, language. This means it evaluates expressions only when it needs their results.

Laziness is one of the things that make Haskell special – really special. Lazy evaluation allows easy handling of infinite data-structures.

The article I wrote yesterday was just the beginning, today we’ll look at the next step in becoming Haskell experts.

Yesterday we’ve learned how to split up our program and how to compile, or run it. Today we’ll look at some basic features of Haskell.

Danger! If you are happy with your current knowledge of programming languages, don’t read on – Haskell might be responsible for some serious defects in your motivation.

I was always some kind of programming language geek. I loved learning and playing around with all kinds of programming languages¹. Currently I’m trying to learn Haskell. Even though I learned functional programming at my university (two semesters using Haskell), I didn’t really learn how to interact with the outside world. This is where things start to get messy, no matter how beautiful the language is.
