The object-oriented programming paradigm centers on using objects to represent real-world entities and their interactions. Objects bundle data (attributes) and methods (functions) to allow for encapsulation, inheritance, and polymorphism. This paradigm simplifies complex coding by promoting code reuse and improving maintainability. Developers can create modular and scalable applications that mimic real-world concepts, making it easier to manage large programs. In addition, object-oriented programming supports the development of software frameworks and libraries, which enable programmers to build upon existing code, reducing development time and enhancing collaboration.
