What are the differences between MVVM and MVC in mobile development?

What are the differences between MVVM and MVC in mobile development?

MVVM (Model-View-ViewModel) and MVC (Model-View-Controller) are both architectural patterns used in mobile development. MVVM separates the development of the graphical user interface from the business logic, while MVC divides the application into three interconnected components. MVVM is often preferred for data-binding and easier testing.

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 to handle the updates.

Which pattern is better for large-scale applications?

For large-scale applications, MVVM is often considered better due to its support for data binding and separation of concerns, which can lead to more maintainable and testable code.

Are there any drawbacks to using MVVM?

Yes, some drawbacks of MVVM include a steeper learning curve for developers unfamiliar with data binding and potential performance issues if not implemented correctly.
