The [[Introduction|Introduction to Haskell]] on the Haskell website tells you what Haskell gives you: substantially increased programmer productivity, shorter, clearer, and more maintainable code, fewer errors, higher reliability, a smaller semantic gap between the programmer and the language, shorter lead times. There is an old but still relevant paper about [http://www.cse.chalmers.se/~rjmh/Papers/whyfp.html Why Functional Programming Matters] (PDF) by John Hughes. More recently, Sebastian Sylvan wrote an article about [[Why Haskell Matters]].

Revision as of 11:40, 8 August 2014


This portal points to places where you can go if you want to learn Haskell.

The Introduction to Haskell on the Haskell website tells you what Haskell gives you: substantially increased programmer productivity, shorter, clearer, and more maintainable code, fewer errors, higher reliability, a smaller semantic gap between the programmer and the language, shorter lead times. There is an old but still relevant paper about Why Functional Programming Matters (PDF) by John Hughes. More recently, Sebastian Sylvan wrote an article about Why Haskell Matters.

There is also a table comparing Haskell to other functional languages. Many questions about functional programming are answered by the comp.lang.functional FAQ.

You can ask questions to members of the Haskell community on mailing lists, IRC, or StackOverflow. We recommend installing the Haskell Platform.
