What are the differences between MVC, MVVM, and MVP?

MVC (Model-View-Controller), MVVM (Model-View-ViewModel), and MVP (Model-View-Presenter) are design patterns used in software development. MVC separates an application into three interconnected components, while MVVM introduces a ViewModel to facilitate data binding. MVP focuses on the presentation layer, with the Presenter acting as a middleman between the Model and View.

Can you explain how data binding works in MVVM?

In MVVM, data binding allows the View to automatically reflect changes in the ViewModel. This is achieved through two-way binding, where changes in the View update the ViewModel and vice versa, reducing the need for manual updates.

Which pattern is better for mobile app development?

It depends on the specific requirements of the app. MVVM is often preferred for mobile apps due to its support for data binding and separation of concerns, making it easier to manage UI and business logic.

Are there any performance differences between these patterns?

Yes, performance can vary. MVC may have less overhead compared to MVVM due to its simpler structure, but MVVM can lead to more maintainable code in larger applications. MVP can also be efficient, but it may require more boilerplate code.
