What are the best practices for using React Window?

When using React Window, it's important to keep the following best practices in mind: 1. Use fixed item sizes for better performance. 2. Avoid unnecessary re-renders by memoizing components. 3. Implement lazy loading for large lists. 4. Use the useWindowSize hook to adjust the number of visible items.

Can you explain why fixed item sizes are important?

Fixed item sizes help React Window calculate the total height or width of the list efficiently, which improves rendering performance and reduces layout calculations.

What is lazy loading and how can I implement it?

Lazy loading is a technique where you load only the items that are currently visible in the viewport. You can implement it in React Window by using the List or FixedSizeList components and specifying the height and itemCount props.

Are there any performance metrics I should monitor?

Yes, you should monitor metrics like render time, frame rate, and memory usage to ensure your application remains performant, especially with large lists.
