The programming paradigm focusing on objects rather than functions is known as object-oriented programming (OOP). OOP emphasizes the use of "objects," which can represent real-world entities and encapsulate both data and methods. This approach enhances code reusability, scalability, and maintainability, making it easier for developers to model complex systems. Key principles of OOP include inheritance, polymorphism, and encapsulation, fostering organized and modular code design.
