Haskell is a standardized, general-purpose purely functional programming language, with non-strict semantics and strong static typing. It is named after the mathematician Haskell Curry. The language is very expressive and has an elegant strong typing system. The language allows you to write code at a very high level, making it easier to write correct code. Because of this, Haskell is particularly useful for writing complex mathematical programs, as well as computer programs that manipulate abstract data types.

The "Haskell" programming language is the most purely functional language ever devised. It has an elegant, concise, highly expressive type system that gives it superior support for software engineering. It allows concise code to be reused in many different scenarios, leading to shorter, clearer, and more maintainable code.

Haskell is a purely functional programming language that is often used for research and development. The Haskell language, defined in the 1990s, has had a profound impact on how people learn to think about computer programs. The paradigm used (functional programming)is different from the traditional models like procedural programming (C) or object orientated programming (Java, C++, C#).

Programming is something you learn by doing, and this course is a collection of programming exercises for the Haskell language. It starts with basic exercises and it gradually increases in complexity.
