Monads are important in Haskell, and they are used in many scenarios. The concept of monads can be confusing at first, but in this chapter, you will learn what monads are and how to use them in complex programs.
Introduction
A monad is a way for values to be used in sequences of computations, resulting in a structure of computations. The sequential building blocks can be used to create computations, and the building blocks themselves can be structured as computations. As the official Haskell documentation ...
