Which design pattern corresponds to the MVVM architecture?

The architectural pattern MVVM (Model-View-ViewModel) corresponds to the design pattern Model-View-ViewModel, which is an evolution of the MVC pattern.

In MVVM:

• Model — contains business logic and data.
• View — responsible for displaying the interface and user interaction.
• ViewModel — acts as an intermediary between Model and View, contains presentation logic and state, and provides two-way data binding.

MVVM can be viewed as an application of the Observer pattern for updating the View when data in the ViewModel changes, as well as using Data Binding for automatic synchronization.

Thus, MVVM is an architectural pattern that combines ideas of separation of concerns and reactive UI updates.
