Implementing Fixed-size List with React-Window

Show how to create a fixed-size list using React-Window, focusing on the 'FixedSizeList' component and its key props for optimal performance.

import React from 'react';
import { FixedSizeList } from 'react-window';

Import React and the FixedSizeList component from react-window.

const Row = ({ index, style }) => (
 <div style={style}>
  {/* Render your item using index to access the item data */}
  `Item ${index}`
 </div>
);

Define the Row component that will render each item in the list. Use the style and index props for styling and accessing the item respectively.

const ListComponent = () => {
 const items = new Array(1000).fill(null).map((_, index) => `Item ${index}`);

 return (
  <FixedSizeList
   height={500}
   width={300}
   itemSize={35}
   itemCount={items.length}
  >
   {Row}
  </FixedSizeList>
 );
};

Create the ListComponent that renders the FixedSizeList. Define the height, width, itemSize, and itemCount props to control the list's appearance and behavior.

export default ListComponent;

Export the ListComponent so it can be used elsewhere in your application.
