What is Haskell?
Haskell, named after logician Haskell Curry, is a functional programming language used in education, research, and industry. Its purely functional nature ensures functions do not alter external variables, providing programming stability. Statically typed with type inference at compile time, Haskell also offers other features like concurrency and lazy evaluation.
