Kas saaksite selgitada MVVM arhitektuurimustri eeliseid ja puudusi?

MVVM (Model-View-ViewModel) is an architectural pattern that separates presentation logic from business logic, improving code testability and maintainability.

Advantages:

• Clear separation of responsibilities: View is only responsible for display, ViewModel for logic and state.
• Improved testability: ViewModel can be tested without UI.
• Two-way data binding simplifies synchronization between UI and data.
• Increases code reusability, especially of ViewModel.

Disadvantages:

• Complexity: for simple screens, the pattern may be excessive.
• Data binding setup can complicate debugging.
• Possibility of memory leaks if references between View and ViewModel are not managed properly.
