Can you explain the differences between architectural patterns MVC, MVP, and MVVM?

MVC, MVP, and MVVM are architectural patterns that help organize application code by separating logic and presentation.

• MVC (Model-View-Controller):

  • Model — data and business logic.
  • View — user interface.
  • Controller — intermediary that handles user input, updates Model and View.

  In MVC, View and Controller are closely linked; Controller directly manages View.

• MVP (Model-View-Presenter):

  • Model — data.
  • View — interface implementing methods for interaction with Presenter.
  • Presenter — contains logic, interacts with Model, updates View via interface.

  In MVP, View is passive; Presenter controls logic and UI updates.

• MVVM (Model-View-ViewModel):

  • Model — data.
  • View — interface.
  • ViewModel — abstraction of View, contains logic and state, binds Model and View.

  MVVM often uses two-way data binding, reducing code in View and Presenter.

Summary:

• MVC — Controller manages View.
• MVP — Presenter manages View via interface.
• MVVM — ViewModel provides data and commands, often with data binding.

Choice depends on project requirements and technologies.
