What is the difference between MVC and MVP? The MVP is evolved from the classic pattern MVC, where the basic ideas are interlinked: Controller/presenter is responsible for the processing of logic, model provides data, and view is responsible for the display. As a new model, there is a significant difference between MVP and MVC: In MVP, view does not use model directly, communication between them is through presenter (Controller in MVC), all interactions occur within presenter, In MVC, view reads data from the direct model rather than through the Controller. In MVC, view is directly accessible to the model! As a result, the view contains the model information and inevitably includes some business logic. In the MVC model, more attention is paid to the constant of the model, while there are several different displays of the model, and the view. So, in the MVC model, models do not depend on view, but view is dependent on model. Not only that, because some business logic is implemented in view, it is difficult to change the view, at least those business logic is not reusable. MVP Advantage 1, the model and the view completely separate, we can modify the view without affecting model 2, can more efficient use of the model, because all the interaction occurs in a place--presenter internal 3, we can use a presenter for multiple views, Without the need to change the logic of presenter. This feature is very useful because view changes are always more frequent than models. 4. If we put logic in presenter, then we can test these logic (unit tests) from the user interface thedisadvantage of the MVP is that because the view is rendered in presenter, the interaction between the views and the presenter is too frequent. It is also important to understand that if presenter renders the view too much, it often makes it more closely related to a particular view. Once the view needs to be changed, the presenter also needs to be changed. For example, the presenter used to render HTML now also needs to be used for rendering PDFs, so the view is likely to need to be changed.
