How do I use react-window for efficient rendering?

You can use react-window to render large lists efficiently by only rendering the items in view. Would you like a code example?

Yes, please provide a code example.

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 ones in view will be rendered.

What are the benefits of using react-window over traditional methods?

The main benefits are improved performance and reduced memory usage, as it only renders visible items, making it ideal for large lists.
