257+ MVC provides maximum control and is very simple to implement, but it has a serious drawback — MVC tends to mix
258+ presentation and interaction logic inside the Controller, which often leads to tightly coupled and harder-to-test code.
259+ For this reason, the following analysis will focus only on MVP and MVVM.

262- Both MVP and MVVM provide a crucial advantage — the ability to test the logic that interacts with the ` Model `
263- independently of the ` View ` , but this is achieved in different ways.
261+ MVP and MVVM are similar in that both patterns introduce an explicit representation of UI state outside of the ` View ` ,
262+ unlike MVC. In MVP, the state is stored in the ` Presenter ` , while in MVVM, the state is stored in the ` ViewModel ` .
263+ It is worth noting that this characteristic makes both patterns significantly more complex compared to MVC.
264264
265- In MVVM, this separation is accomplished by moving UI state into the ` ViewModel ` , which requires creating and
266- maintaining a dedicated representation of the UI state. In JavaFX, this often leads to a significant amount of
267- additional code and increased architectural complexity, especially in cases where the state of the ` View ` is
268- difficult to express exclusively through bindings.
269-
270- In contrast, MVP does not require duplicating the ` View ` state. The ` Presenter ` can directly invoke methods on the
271- ` View ` through an interface, which makes the pattern more flexible and allows it to naturally handle situations
272- where updating the UI through state or bindings proves to be awkward or insufficient.
273-
274- The second important difference is testability. MVVM excels at testing data-driven, state-oriented logic, which
275- makes it particularly well suited for CRUD-style screens where the UI is a deterministic projection of state.
276- However, this advantage is limited to scenarios where the UI behavior is state-driven.

281+
282+ From a testability perspective, MVVM has an advantage over MVP because the ` ViewModel ` is an ideal unit for testing.
283+ In contrast, in MVP you need to mock the ` View ` in every ` Presenter ` test, which introduces boilerplate.
284+
285+ Conceptually, MVVM is centered around modeling UI as a projection of state, while MVP models UI behavior as an explicit
286+ sequence of interactions. The more deterministic and state-driven the UI is, the more natural MVVM becomes. The
287+ more procedural and interaction-driven it is, the more natural MVP becomes.
