MVVM vs Other Architectures

Kotlin and Jetpack Compose favor MVVM (Model-View-ViewModel) because it offers better separation of concerns, making UI more reactive and business logic more manageable. Here's why MVVM is preferred over older patterns:

🔍 Comparison of MVVM vs. Other Architectures

Architecture	UI Logic	Business Logic	Testability	Code Separation	Lifecycle Handling
MVC (Model-View-Controller)	Controller tightly coupled to View	Business logic mixed with UI	Harder due to View-Controller coupling	Weak separation	Controller struggles with lifecycle
MVP (Model-View-Presenter)	Presenter decouples View from logic	Business logic in Presenter	Better, but Presenter can get bloated	Decent separation	Presenter still manually handles lifecycle
Viper	Clear responsibility via different layers	Strong business logic separation	Excellent	Overly complex for many apps	Good lifecycle separation
MVVM (Model-View-ViewModel)	ViewModel mediates between View and Model	UI state stored properly	Best due to ViewModel unit testing	Best separation with ViewModel handling UI state	ViewModel survives configuration changes

🔥 Why Kotlin & Jetpack Compose Prefer MVVM

✅ ViewModel survives lifecycle changes (screen rotations).

✅ Cleaner state management with StateFlow, LiveData, or MutableState.

✅ Encourages reactive UI updates (Jetpack Compose benefits greatly).

✅ Works smoothly with Coroutines & Flows for async tasks.

✅ Minimizes UI logic in Views, leading to scalable and maintainable apps.

MVP and MVC struggle with tight coupling, making state harder to manage, while MVVM ensures separation and flexibility—making it ideal for Jetpack Compose in Kotlin. 🚀
