Using Refs vs State in React

What’s the difference between using refs and state in React?

Refs are used to access DOM elements directly, while state is used to manage component data and trigger re-renders.

When should I use refs instead of state?

Use refs when you need to interact with the DOM directly, like focusing an input, without causing a re-render.

Can you give me an example of using refs?

Sure! You can create a ref using const myRef = useRef(null); and then attach it to an element like <input ref={myRef} />.

What about performance? Is one better than the other?

Refs can be more performant for certain tasks since they don't trigger re-renders, but state is essential for managing UI updates.
