What are the differences between optimistic and pessimistic UI?
Optimistic UI assumes that actions will succeed and updates the interface immediately, while pessimistic UI waits for confirmation before updating.
Can you give me an example of each?
Sure! In an optimistic UI, when you send a message, it appears in the chat immediately. In a pessimistic UI, the message appears only after it's confirmed sent.
What are the pros and cons of each approach?
Optimistic UI provides a smoother experience but can mislead users if actions fail. Pessimistic UI is more reliable but can feel slower.
Which approach is better for mobile apps?
It depends on the app's context. Optimistic UI is great for chat apps, while pessimistic UI might be better for banking apps where accuracy is crucial.
