What is the difference between refs and state in React?
An example of an AI chatbot conversation about understanding 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 state instead of refs?
Sure! Use state for form inputs where you want to track user input, and refs for focusing an input element.
Are there any performance implications when using state?
Yes, frequent updates to state can cause re-renders, which may impact performance. Use refs for non-visual data.
How do I create a ref in a functional component?
You can create a ref using the useRef hook. For example: const myRef = useRef(null); and then attach it to an element.
