 لاحظ أن بعض مكونات `Item` لديها خاصية `isPacked` معينة إلى `true` بدلا من `false`. ترغب في إضافة علامة التحقق (✔) إلى العناصر المحزومة في حالة `isPacked={true}`.

 There are two problems with this code.
 
-One problem is that it is very inefficient: the component (and its children) have to re-render between each `set` call in the chain. In the example above, in the worst case (`setCard` → render → `setGoldCardCount` → render → `setRound` → render → `setIsGameOver` → render) there are three unnecessary re-renders of the tree below.

-Even if it weren't slow, as your code evolves, you will run into cases where the "chain" you wrote doesn't fit the new requirements. Imagine you are adding a way to step through the history of the game moves. You'd do it by updating each state variable to a value from the past. However, setting the `card` state to a value from the past would trigger the Effect chain again and change the data you're showing. Such code is often rigid and fragile.
