An example of an AI chatbot conversation about React.memo in React.js.
What is React.memo?
React.memo is a higher-order component that optimizes functional components by memoizing their output.
How does it improve performance?
It prevents unnecessary re-renders by only re-rendering the component if its props change.
Can you give me an example of how to use it?
Sure! You can wrap your functional component like this: const MyComponent = React.memo((props) => { /* component code */ });.
Are there any downsides to using React.memo?
Yes, if used improperly, it can lead to performance issues, especially if the props are complex objects.
