| December 01, 2010 | |
| The Y Combinator is a method of implementing recursion in a programming language that does not support it natively (actually, it's used more for exercising programming brains). The requirement, though, is that language to support anonymous functions. | |
| I chose JavaScript for deriving the Y Combinator, starting from the definition of a recursive factorial function, using a step-by-step transformation over the initial function. | |
| Update | |
| There's now a Chinese translation of this article as well as a Clojure port. |
