Haskell and Morrison: The Proven Strategies You’re Not Using

Based on lambda calculus, Haskell is a purely functional programming language that features referential transparency, immutability and lazy evaluation. Concepts that will blow your mind — relearn programming while having an absolute blast. Reason about large pieces of code and compose them easily.

Haskell (/ ˈhæskəl / [25]) is a general-purpose, statically typed, purely functional programming language with type inference and lazy evaluation. [26][27] Haskell pioneered several programming language features including type classes for type-safe operator overloading and monadic input/output (IO). It is named after logician Haskell Curry.

Haskell Free Library & Opera House Founded in 1901, the Haskell Free Library & Opera House supports the cultural needs of the community on both sides of the Canada-U.S. border, in both English and French, through access to information, reading material, a broad range of library services, and programming, as well as the visual and performing arts.

Haskell is an advanced purely-functional programming language. An open-source product of more than twenty years of cutting-edge research, it allows rapid development of robust, concise, correct software.

CIS194 is the introductory Haskell course of the University of Pennsylvania; it is free, thorough, practical and will guide you from the basics to advanced features of the language.

Most Haskell projects can be built using Cabal, but some might require Stack. Installing both guarantees that you can use either, and while following a tutorial or book you can use whatever they recommend.
