How do refs and state differ in React?

In React, state is used to manage data that changes over time, while refs are used to access DOM elements directly.

Can you give an example of when to use refs instead of state?

Sure! Use refs for accessing a DOM element's value directly, like focusing an input field, without triggering re-renders.

What are the performance implications of using state vs refs?

Using state can trigger re-renders, which may affect performance if done excessively. Refs do not cause re-renders, making them more efficient for certain tasks.

Are there any scenarios where using both is beneficial?

Yes, you can use state to manage the UI and refs to interact with the DOM directly, providing a balance between reactivity and direct manipulation.
