How do I implement react-window for virtualized lists?

To implement react-window, first install it using npm or yarn. Then, create a component that uses the FixedSizeList or VariableSizeList.

Can you show me a basic example of using FixedSizeList?

Sure! Here's a simple example:

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

const Row = ({ index, style }) => <div style={style}>Row {index}</div>;

const MyList = () => (
  <List
    height={150}
    itemCount={1000}
    itemSize={35}
    width={300}
  >
    {Row}
  </List>
);

What if I need variable row heights?

You can use VariableSizeList instead. You'll need to provide a function to determine the height of each row.

Are there any performance tips for using react-window?

Yes! Make sure to keep your row components lightweight and avoid unnecessary re-renders by using memoization.
