What is object-oriented programming (OOP) primarily based on?

Object-oriented programming (OOP) is primarily based on the concept of objects, which are instances of classes. In OOP, an object encapsulates both data (attributes) and code (methods) that operate on that data. This allows for a more modular and organized approach to programming, where code is structured around the concept of objects rather than just functions or procedures.

This object-centric approach enables developers to model real-world entities more intuitively and encourages reuse through inheritance and polymorphism, allowing for more flexible and maintainable code. The design principles of OOP—such as encapsulation, abstraction, inheritance, and polymorphism—are fundamentally rooted in how objects interact and collaborate within a program, making them central to the OOP paradigm.
