The Functor is a functional programming concept, taken from Category Theory, often viewed from a problematic area: you either come across people who want to show how much they are above the rest (resulting in esoterizing explanations), or people who don't want to hear about it because… of the former, quite often.

However.

This concept is useful and promising, as well as being simple (especially for a developer, who works with structures every day).

Wanna get rid of your apprehension once and for all? Here is an explanation in pictures of what a Functor is.
