Efekt içinde `count` okumak yerine, React'e bir `c => c + 1` komutu ("bu sayıyı artır!") iletirsiniz. React bunu bir sonraki render'da uygulayacaktır. Ve artık Efektinizin içinde `count` değerini okumanıza gerek olmadığından, Efektinizin bağımlılıklarını boş tutabilirsiniz (`[]`). Bu, Efektinizin her tikte aralığı yeniden oluşturmasını önler.
=======
Instead of reading `count` inside the Effect, you pass a `c => c + 1` instruction ("increment this number!") to React. React will apply it on the next render. And since you don't need to read the value of `count` inside your Effect anymore, you can keep your Effect's dependencies empty (`[]`). This prevents your Effect from re-creating the interval on every tick.

This solves the problem. Note that you had to *remove* `theme` from the list of your Effect's dependencies, because it's no longer used in the Effect. You also don't need to *add* `onConnected` to it, because **Effect Events are not reactive and must be omitted from dependencies.**

The function passed to `startTransition` is called the "Action". You can update state and (optionally) perform side effects within an Action, and the work will be done in the background without blocking user interactions on the page. A Transition can include multiple Actions, and while a Transition is in progress, your UI stays responsive. For example, if the user clicks a tab but then changes their mind and clicks another tab, the second click will be immediately handled without waiting for the first update to finish.

To give the user feedback about in-progress Transitions, to `isPending` state switches to `true` at the first call to `startTransition`, and stays `true` until all Actions complete and the final state is shown to the user. Transitions ensure side effects in Actions to complete in order to [prevent unwanted loading indicators](#preventing-unwanted-loading-indicators), and you can provide immediate feedback while the Transition is in progress with `useOptimistic`.

This is expected, because Actions within a Transition do not guarantee execution order. For common use cases, React provides higher-level abstractions like [`useActionState`](/reference/react/useActionState) and [`<form>` actions](/reference/react-dom/components/form) that handle ordering for you. For advanced use cases, you'll need to implement your own queuing and abort logic to handle this.
