What are the differences between refs and state in React?
An example of an AI chatbot conversation about React's refs and state differences.
Can you explain the differences between refs and state in React?
Sure! In React, state is used to manage data that changes over time, while refs are used to access DOM elements directly.
When should I use state instead of refs?
You should use state when you need to trigger a re-render of the component based on data changes. Use refs for accessing DOM nodes or storing mutable values that don't require re-rendering.
Can you give an example of when to use refs?
Absolutely! A common use case for refs is to focus an input field when a component mounts. You can create a ref and attach it to the input element.
What about performance? Is one better than the other?
In terms of performance, using state can lead to more re-renders, while refs do not cause re-renders. So, for non-visual data, refs can be more efficient.
