Why

Separation into layersDuring the development process, developers and designers can work more independently and concurrently on their components. The designers can concentrate on the view they can easily generate sample data to work with, while the developers can work on the view model/controller/presenter and model components.

Easy test creationThe developers can create unit tests for the view model and the model without using the view. The unit tests for the view model can exercise exactly the same functionality as used by the view.

UI independency from business logic (MVVM)

It is easy to redesign the UI of the application without touching the code because the view is implemented separately. A new version of the view should work with the existing view model.

AdaptorIf there is an existing implementation of the model that encapsulates existing business logic, it may be difficult or risky to change. In this scenario, the view model acts as an adapter for the model classes and enables you to avoid making any major changes to the model code.
