Writing in an FP style makes life so much easier… or at least that is what we keep hearing. But how can that be true if we can’t even understand what the FP people are talking about? Maybe the last time you had a chance to really catch up with the FP world was when you picked up maps, and filters, and you see real value, but now the lingo has changed again and you haven’t quite had the time to get it all sorted in your head. In this talk we will learn about things like Free, Co, Monads, Lenses, Morphisms, and other terms that may help you as you are trying to make your Ruby more functional, or picking up new languages with functional concepts.
