What is the difference between state and refs in React?
An example of an AI chatbot conversation about the differences between state and refs in React.
What is the difference between state and refs 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, while refs are better for focusing an input element.
Are there any performance implications when using state vs refs?
Yes, using state can trigger re-renders, which may affect performance. Refs do not cause re-renders, making them more efficient for certain tasks.
Can I use refs to store mutable values?
Yes, refs can hold mutable values without causing re-renders, making them suitable for storing values that don't need to trigger updates.
