Testability:- The ViewModel is easier to unit test than code-behind or event-driven code.As the code base will increase over the course of time, this will help you to distinguish between them. Maintainability:- The presentation layer and the logic are loosely coupled, due to this code is easily maintainable and reusable.There are three key things that flow out of applying MVVM − What it means in real terms is that when your model needs to change, it can be changed easily without the view needing to and vice-versa. The key benefit is allowing true separation between the View and Model and the efficiency that you gain from having that. ViewModel is the mediator between View and Model which carry all user events and return back the result. MVVM is useful to move business logic from view to ViewModel and Model. Here I am going to explain MVVM with a simple example that will give you enough knowledge to implement in your application. MVVM is one of them which is able to segregate business logic from UI, this looks easy job to do, but my friend believe me if you missed something in architecture or doing anything inaccurate then be ready for big trouble at a later stage of application development, and eventually you will end up having some code hack in application to do your job. We need one architecture to be placed in the application which communicates between UI and business logic.
