What are the differences between MVP and MVVM?

What are the differences between MVP and MVVM?

MVP (Model-View-Presenter) and MVVM (Model-View-ViewModel) are both architectural patterns used in software development. MVP separates the presentation layer from the business logic, while MVVM allows for a more decoupled approach, especially in data binding.

Can you explain how data binding works in MVVM?

In MVVM, data binding allows the View to automatically reflect changes in the ViewModel. This means that when the data in the ViewModel changes, the View updates automatically without needing to write additional code.

Which pattern is better for mobile app development?

It depends on the specific requirements of your app. MVVM is often preferred for mobile apps due to its support for data binding and easier testing, while MVP can be simpler for smaller applications.

Are there any drawbacks to using MVVM?

Yes, MVVM can introduce complexity, especially in managing bindings and ensuring that the ViewModel remains clean and testable. It may also require more boilerplate code compared to MVP.
