What is the difference between MVVM (Model-View-ViewModel) and MVC (Model-View-Controller) architectural patterns?

Question

Accepted Answer

MVVM separates the view and model using a ViewModel, while MVC separates the view and model using a controller.

In MVVM, the ViewModel acts as an intermediary between the view and model, handling user interactions and updating the model accordingly.
In MVC, the controller is responsible for handling user input, updating the model, and updating the view.
MVVM allows for better separation of concerns and easier unit testing of the ViewModel.
MVC can lead to tighter coupling between the view and controller, making it harder to test in isolation.
An example of MVVM is Android's LiveData and ViewModel components, while an example of MVC is the traditional web application architecture.
