Saved with the link. Notes from 2007 to 2016 are mostly the page's own words, so this is probably an excerpt.
Haskell is a general purpose, purely functional programming language featuring static typing, higher order functions, polymorphism, type classes, and monadic effects. Haskell compilers are freely available for almost any computer.
