The '''Joy programming language''' is a simple [[functional programming language]] that was produced by Manfred von Thun of [[Latrobe University]] in [[Melbourne]], [[Australia]]. Joy is based on composition of functions rather than [[lambda calculus]]. It has turned out to have many similarities to [[Forth programming language|Forth]], due less to design than to a sort of parallel evolution and convergence.

=== Joy ===

Joy is a simple [[functional programming language]] which is almost unique (besides perhaps [[unlambda]]) in its lack of a [[lambda]] operator, and therefore lack of [[Parameter (computer science)|formal parameters]]. To illustrate this with a common example, here's how the square function might be defined in an [[imperative programming language]] ([[C programming language|C]]):

int square(int x) {
