💻 Usage

Here's a simple example of how to use the VirtualizedList component:

import React from 'react';
import { VirtualizedList } from 'virtualized-react';

const App = () => {
  // Create an array of 1000 items
  const items = Array(1000).fill(null).map((_, index) => (
    <div key={index}>
      <h3>Item {index + 1}</h3>
      <p>This is a list item with dynamic content</p>
    </div>
  ));

  return (
    <div style={{ height: '400px' }}>
      <VirtualizedList items={items} />
    </div>
  );
};

export default App;

🎯 Props

| Prop | Type | Description | Required | | ----- | ------------- | -------------------------------------- | -------- | | items | JSX.Element[] | Array of React elements to be rendered | Yes |

• Optimal performance with up to 10,000+ items.

🌟Advanced Usage

import React from 'react';
import { VirtualizedList } from 'virtualized-react';

const AdvancedExample = () => {
  const complexItems = Array(1000).fill(null).map((_, index) => (
    <div key={index}>
      <h3>Complex Item {index + 1}</h3>
      <div style={{ padding: '10px' }}>
        <img src={`https://placekitten.com/50/50?image=${index}`} alt="Cat" />
        <p>Some dynamic content that can vary in height</p>
        {index % 2 === 0 && (
          <div>Extra content that appears in some items</div>
        )}
      </div>
    </div>
  ));

  return (
    <div style={{ height: '600px', width: '100%', maxWidth: '800px' }}>
      <VirtualizedList items={complexItems} />
    </div>
  );
};
