Download Haskell. Real World Haskell. Introduction. Haskell is a computer programming language. In particular, it is a polymorphically statically typed, lazy, purely functional language, quite different from most other programming languages. The language is named for Haskell Brooks Curry, whose work in mathematical logic serves as a foundation for functional languages. Haskell is based on the lambda calculus, hence the lambda we use as a logo. 1 Why use Haskell? Writing large software systems that work is difficult and expensive. WOW! Even if you are not in a position to use Haskell in your programming projects, learning Haskell can make you a better programmer in any language. I learned Haskell a couple of years ago, having previously programmed in Python and (many) other languages.
Haskell offers you: Substantially increased programmer productivity (Ericsson measured an improvement factor of between 9 and 25 using Erlang, a functional programming language similar to Haskell, in one set of experiments on telephony software). 3.4 Brevity. Haskell. Why Functional Programming Matters. Learn You a Haskell for Great Good! Introduction - Learn You a Haskell for Great Good!
About this tutorial Welcome to Learn You a Haskell for Great Good! If you're reading this, chances are you want to learn Haskell. Well, you've come to the right place, but let's talk about this tutorial a bit first. I decided to write this because I wanted to solidify my own knowledge of Haskell and because I thought I could help people new to Haskell learn it from my perspective.
There are quite a few tutorials on Haskell floating around on the internet. When I was starting out in Haskell, I didn't learn from just one resource. This tutorial is aimed at people who have experience in imperative programming languages (C, C++, Java, Python …) but haven't programmed in a functional language before (Haskell, ML, OCaml …). The channel #haskell on the freenode network is a great place to ask questions if you're feeling stuck.
I failed to learn Haskell approximately 2 times before finally grasping it because it all just seemed too weird to me and I didn't get it. So what's Haskell? The Haskell 98 Language Report. Hackage: Introduction.
