Haskell reference

This is our Haskell encyclopedia, an interlinked collection of standalone articles that each covers a single topic.In contrast, our courses consist of longer sequences of lessons, and each course weaves together a variety of topics.

Also see Haskell tooling, a collection of articles about software to help you be more productive in Haskell.

We try to keep each article approachable, though some have prerequisites. For Haskellers of any level, these are useful as reference and review. Haskellers of all levels will find something new to learn here as well.
