OOP vs functional programming¶

Object Oriented Programming¶

In OOP approuch the code is organized into classes where each has has class has several methods.

Each of these methods will operate on their local instance variables (properties).

For example of a deck of cards, there would be 2 classes - one will be Deck and one will be Card. The deck instance would hold a list of Card instances and provide several methods of managing them.

Functional programming¶

In functional programming, the functions are organized into modules, there is no concept of a class or it's instance.

The modules cannot be copied or instantiated, they are used only as collections of methods.

For example, there might be a method in the Cards module that deals with shuffleing cards. It will accept input of list of strings that represent cards and return this list shuffled.
