What are the differences between MVC and MVVM architectural patterns?

What are the differences between MVC and MVVM architectural patterns?

MVC (Model-View-Controller) separates an application into three main components: the model, the view, and the controller. MVVM (Model-View-ViewModel) also separates concerns but introduces a ViewModel to facilitate data binding between the view and the model. This allows for a more decoupled architecture.

Can you explain how data binding works in MVVM?

In MVVM, data binding allows the ViewModel to communicate with the View. Changes in the ViewModel automatically update the View and vice versa, often using frameworks like WPF or Angular. This reduces the need for manual updates and enhances maintainability.

Which pattern is better for large-scale applications?

For large-scale applications, MVVM is often preferred due to its support for data binding and separation of concerns, which can lead to better maintainability and testability. However, the choice depends on specific project requirements.

Are there any scenarios where MVC might be more suitable?

Yes, MVC can be more suitable for simpler applications or when rapid development is needed, as it has a more straightforward structure. It's also widely used in web applications, especially with frameworks like Ruby on Rails.
