What is MVVM?

MVVM stands for Model-View-ViewModel, which is a software architectural pattern commonly used in application development, especially in frameworks like WPF, Xamarin, and SwiftUI. It separates the development of the graphical user interface (the View) from the business logic or back-end logic (the Model) by introducing an intermediate component called the ViewModel. This separation makes code more maintainable, testable, and scalable. Developers can work on the UI and business logic independently, making the development process more efficient. MVVM also facilitates data binding, which helps keep the UI and underlying data in sync automatically.
