What are the differences between MVC and MVP?

MVC (Model-View-Controller) and MVP (Model-View-Presenter) are both architectural patterns used in software development. MVC separates the application into three components: the Model, which handles data; the View, which displays the data; and the Controller, which manages user input. In contrast, MVP also separates the application into three components, but the Presenter takes on the role of handling the logic and updating the View, making it more testable.

Can you explain how the data flow works in each pattern?

In MVC, the flow starts with the user interacting with the View, which sends input to the Controller. The Controller then updates the Model, and the Model notifies the View to refresh. In MVP, the View sends user input to the Presenter, which updates the Model. The Presenter then updates the View directly, allowing for a more decoupled architecture.

Which pattern is better for mobile app development?

It depends on the specific requirements of the app. MVC is often preferred for its simplicity and ease of use, while MVP can provide better testability and separation of concerns, which can be beneficial in larger applications.

Are there any real-world examples of applications using these patterns?

Yes, many web applications use MVC, such as those built with Ruby on Rails or ASP.NET. MVP is commonly used in Android development, where the Presenter can help manage the lifecycle of the View.
