An example of an AI chatbot conversation about the difference between refs and state in React.
What is the difference between refs and state 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 me an example of when to use refs?
Sure! You might use refs when you need to focus an input field or measure the size of a DOM element.
Is it possible to update the UI using refs?
No, refs do not trigger re-renders. For UI updates, you should use state.
What are the performance implications of using state vs refs?
Using state can lead to more re-renders, while refs can be more performant for direct DOM manipulations without re-rendering.
