This chapter covers the Simple Factory pattern.
Definition
Create an object without exposing the instantiation logic to the client.
Concept
In object-oriented programming, a factory is such an object that can create other objects. A factory can be invoked in many different ways but most often, it uses a method that can return objects with varying prototypes. Any subroutine that can help us to create these new objects, can be considered as a factory. Most importantly, it will help you to abstract the process of object creation from the consumers of the application.
