Object-oriented programming, also referred to as OOP, is a programming paradigm that includes, or relies, on the concept of classes and objects.

The basic entities in object-oriented programming are classes and objects.

Programming isn’t much use if you can’t model real-world scenarios using code, right? This is where object-oriented programming comes.

The basic idea of OOP is to divide a sophisticated program into a number of objects that talk to each other.

Objects in a program frequently represent real-world objects.

It is also possible for objects to serve application logic and have no direct, real-world parallels. They manage things like authentication, templating, request handling, or any of the other myriad features needed for a practical application.
