How can I improve the performance of my React app using react-window?

You can use react-window to efficiently render large lists and tables by only rendering visible items. This reduces the number of DOM nodes and improves performance.

What are the main benefits of using react-window over other libraries?

React-window is lightweight and offers better performance for large datasets compared to libraries like react-virtualized. It also has a simpler API.

Can you show me a basic example of how to implement react-window?

Sure! Here's a simple example:

import { FixedSizeList as List } from 'react-window';

const MyList = () => (
  <List
    height={150}
    itemCount={1000}
    itemSize={35}
    width={300}
  >
    {({ index, style }) => <div style={style}>Item {index}</div>}
  </List>
);

This will render a list of 1000 items, but only the visible ones will be rendered.

Are there any performance tips when using react-window?

Yes! Make sure to set the item size correctly, avoid unnecessary re-renders, and consider using memoization for item components.
