MVVM (Model-View-ViewModel) is a software design pattern that separates the user interface of an application from its business logic and data model.

Model

The model represents the data model of the application and is responsible for data access.

View

The view is the user interface that displays the data and receives user input.

ViewModel

The view model is an intermediate layer that binds the model and the view together. It is responsible for handling user interface interactions and passing data from the model to the view, primarily dealing with the business logic.

The purpose of the MVVM pattern is to enable developers to separate the user interface from the business logic, making the development process more straightforward and flexible. It also facilitates testing and maintenance. A quick introduction is provided in the following video:
