Angular MVVM

Differences to MVP. MVVM uses data binding and is therefore a more event driven architecture . MVP typically has a one to one mapping between the presenter and the view, while MVVM can map many views to one view model In MVVM the view model has no reference to the view, while in MVP the view knows the presenter.

The MVVM pattern presents a better separation of concerns by adding view models to the mix . The view model translates the data of the model layer into something the view layer can use. The controller is no longer responsible for this task.

Both MVP and MVVM are derivatives of MVC. The key difference between MVC and its derivatives is the dependency each layer has on other layers, as well as how tightly bound they are to each other . In MVC, the View sits on top of our architecture with the controller beside it.

The main difference between MVC and MVT is that in a Model View Controller pattern, we have to write all the control specific code. But in an MVT, the controller part is taken care of by the framework itself .

KEY DIFFERENCE In MVC, controller is the entry point to the Application, while in MVVM, the view is the entry point to the Application . MVC Model component can be tested separately from the user, while MVVM is easy for separate unit testing, and code is event-driven.17 Mar 2022

The difference between the MVC and MVVM is View and controller are responsible for calculating the value and assigning the value so the load is more on View and Controller where in MVVM View and Controller are only responsible for assigning the value not calculating the value.
