# FP CONCEPTS 

# 1. FUNCTOR:

* A Functor is a datatype that preserves structure and implements the map function.

* Preserving structure simply means that you can put a value inside and the structure itself won’t change it.

* Map (or mapper/fmap) is a function that takes a function as an argument and applies that function to the values in the structure it operates on.

# 2. MONAD:

* A monad is a structure that combines program fragments (functions), and wraps their return values in a type with additional computation.

* Example from java java.util.Optional - Monad

# 3. MONOIDS:

* A Monoid is a design pattern expressing function composition of items in a set, 

is a function that takes two arguments and returns an argument of that type and it supports both the identity property.

**Pure functions ;]**

# IN KOTLIN:

* A higher-order function is a function that takes one or more functions as arguments or returns a function as a result. 

* In Kotlin, We can define higher-order functions using lambda expressions. `( (A, B) -> C )`.

* Example from kotlin functor `fold`.

* A pure function doesn't depend on anything other than its input parameters.
