MVVM (Model-View-ViewModel)

MVVM, which stands for Model-View-ViewModel, is a popular software architectural pattern used in application development. It provides a structured and organized approach to building user interfaces (UIs) by separating the UI presentation logic from the business logic and data manipulation.

The MVVM pattern consists of three main components:

1. Model: The Model represents the data and business logic of the application. It encapsulates the data structures, algorithms, and rules that govern the behavior of the application.
2. View: The View is responsible for presenting the UI to the user. It defines the layout, appearance, and visual elements of the UI.
3. ViewModel: The ViewModel serves as the intermediary between the View and the Model. It contains the presentation logic and exposes data and commands that the View can bind to. The ViewModel also notifies the View of any changes in the underlying data, ensuring that the UI stays up to date.

By separating the UI logic from the business logic, MVVM enables better code organization, modularization, and testability. It promotes separation of concerns, making it easier to maintain and evolve the application over time.
