What are the differences between the MVC and MVVM architectural patterns, and in what scenarios should each be used?

Question

Accepted Answer

MVC focuses on separating data, presentation, and logic, while MVVM adds a ViewModel layer to enhance data binding and separation of concerns.

MVC: Model-View-Controller pattern separates data, presentation, and logic. Views directly interact with Models and Controllers.
MVVM: Model-View-ViewModel pattern adds a ViewModel layer between the View and Model to enhance data binding and separation of concerns.
MVC is more traditional and widely used, while MVVM is gaining popularity for its improved testability and maintainability.
MVVM is often preferred for complex UIs with a lot of data binding requirements, while MVC may be simpler for smaller projects.
Example: An e-commerce app with complex product listings and filtering might benefit from MVVM, while a simple calculator app could use MVC.
