What is 'Currying'?

Question

I\'ve seen references to curried functions in several articles and blogs but I can\'t find a good explanation (or at least one that makes sense!)

Answer 1

I found this article, and the article it references, useful, to better understand currying: http://blogs.msdn.com/wesdyer/archive/2007/01/29/currying-and-partial-function-application.aspx

As the others mentioned, it is just a way to have a one parameter function.

This is useful in that you don't have to assume how many parameters will be passed in, so you don't need a 2 parameter, 3 parameter and 4 parameter functions.
