Functors - What are they?

In this article we will be looking at a concept in FP called functor.

A functor might sound very strange and esoteric but chances are you have used it in some ways. Some of you probably a lot! In this article we will look at what they are and some reasons they are usefull.

Lets start with a definition of a functor and then try to make sense of it. This will not be a comprehensive explanation and we will be glossing over some details for in the interest of brevity but it will hopefully be enough you get you started.

"A functor is a structure with one (or more) values in it that has a function that can transform the value".
