Functional programming quick start

Functional programming lends its features to code that is simple, concise, less error-prone and easier to grasp. It has seen a major rise in recent years not by accident. However, even A-players with an object-oriented background can struggle with the shift in paradigm. We provide a comprehensive quick start to get your team up and running.
