Monads

A Monad is a type of Functor, a type that, along with map, implements the flatMap function. It is simple, right? We have a Functor with an extra functionality, and that's the flatMap implementation. So, any types that we can call map and flatMap functions over are Monads. Arrays and optionals are examples of Monads.

Monads are Functors with flatMap functions! In the following sections, we will talk about map and flatMap functions.

So far, we have learned that Functors are structures with map functions. Applicative Functors are Functors with apply functions and Monads are Functors with flatMap functions. Now, let's talk about these important functions.
