(language) A functional programming language by Manfred von Thun. Joy is unusual because it is not based on lambda calculus, but on the composition of functions. Functions take a stack as argument, consume any number of parameters from it, and return it with any number of results on it. The concatenation of programs denotes the composition of functions. One of the datatypes of Joy is that of quoted programs, of which lists are a special case.Joy Home.
