How can I use the useState hook effectively in React?

The useState hook is essential for managing state in functional components. You can use it to store values and update them.

Can you give me an example of using useState with an object?

Sure! You can initialize state with an object like this: const [state, setState] = useState({ count: 0 }); Then, update it using setState({...state, count: state.count + 1});.

What about using useState with arrays?

For arrays, you can initialize it like const [items, setItems] = useState([]); To add an item, use setItems([...items, newItem]);.

Are there any performance considerations I should be aware of?

Yes, avoid unnecessary re-renders by batching state updates and using functional updates when the new state depends on the previous state.
