The Joy programming language in computer science is a purely functional programming language that was produced by Manfred von Thun of La Trobe University in Melbourne, Australia. Joy is based on composition of functions rather than lambda calculus. It was inspired by the function-level programming style of John Backus's FP.[1] It has turned out to have many similarities to Forth, due not to design but to an independent evolution and convergence.[citation needed]

In the early 1980s I came across the famous Backus paper "Can programming be liberated from the von Neumann style," and I was immediately intrigued by the higher level of programming in his FP.
