## Definition

Stands for Model-View-ViewModel. A way of organizing computer code that keeps the data, the visual design, and the logic in separate parts to make apps easier to build and test.

For teachers: Abbreviation for Model-View-ViewModel. An architectural pattern used in software engineering that facilitates the separation of the development of the graphical user interface from the development of the business logic or back-end logic.

## Examples

- The team used MVVM to build the new mobile app.
- By adopting the MVVM pattern, the developers were able to write unit tests for the logic without needing to launch the user interface.
- Implementing MVVM allows for a clean separation of concerns, where the ViewModel acts as a value converter that exposes data objects from the Model in a way that the View can easily manage.

## Usage notes

- Commonly used in the context of modern UI frameworks like WPF, Xamarin, or SwiftUI.
