The Object-Oriented Programming methodology introduces the principles of inheritance, encapsulation, abstraction, and polymorphism through the use of classes and objects. The goal of OOP is to connect data and functions in order to increase code stability and security. Every developer can write code that works, but if you want to be a rock star developer, you have to write code that is Understandable, Readable, Changeable, Extensible, and Maintainable.
