What are the differences between MVVM and MVC?

What are the differences between MVVM and MVC?

MVVM (Model-View-ViewModel) and MVC (Model-View-Controller) are both architectural patterns used in software development. The main difference lies in how they separate concerns. In MVC, the controller handles user input and updates the model, while in MVVM, the ViewModel acts as a bridge between the view and the model, allowing for more data binding.

Can you explain how data binding works in MVVM?

Sure! 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 applications?

It depends on the specific needs of the application. MVVM is often preferred for large applications with complex user interfaces because it promotes a clear separation of concerns and easier testing. MVC can be simpler and more straightforward for smaller applications.

Are there any frameworks that support MVVM?

Yes, several frameworks support MVVM, including WPF (Windows Presentation Foundation), Xamarin, and Angular. These frameworks provide built-in support for data binding and other MVVM features.
