Yale University.Department of Computer Science.Version 2.4 (February 22, 2012).In the year 2000 I wrote a book called The Haskell School of Expression
– Learning Functional Programming through Multimedia [Hud00 ]. In that
book I used graphics, animation, music, and robotics as a way to motivate
learning how to program, and specifically how to learn functional program-
mingusing Haskell, a purely functional programming language. Haskell
is quite a bit different from conventional imperative or object-oriented
languages such as C, C++, Java, C#, and so on. It takes a different mind-set
to program in such a language, and appeals to the mathematically inclined
and to those who seek purity and elegance in their programs. Although
Haskell was designed over twenty years ago, it has only recently begun to
catch on in a significant way, not just because of its purity and elegance,
but because with it you can solve real-world problems quickly and efficiently,
and with great economy of code.
