Q: How does OOP facilitate the development of web applications?  

Object-oriented programming (OOP) facilitates the development of web applications by enabling the creation of reusable components and services. In OOP, web application components such as controllers, models, and views can be encapsulated within classes, each responsible for specific functionality. This modular approach promotes code reuse and maintainability, as components can be easily reused across different parts of the application or even in different projects. For example, a "User" class can encapsulate user-related data and behaviors, such as authentication and profile management, which can then be reused in various parts of the application. OOP also supports the creation of services that encapsulate business logic, making it easier to manage and test complex operations. Inheritance allows for the extension of existing components, adding new features without modifying the original code. Polymorphism enables flexible interactions between different components, enhancing the scalability of the application. Overall, OOP's principles of encapsulation, inheritance, and polymorphism make it an effective paradigm for developing robust, scalable, and maintainable web applications.
