Ever wondered how Instagram, LinkedIn, or YouTube keep loading content without making you click "Next Page"?

That's Infinite Scroll.

Instead of loading thousands of items at once, React fetches new data only when you reach the end of the current list. The result? Faster apps, lower memory usage, and a much smoother user experience.

In this cheat sheet, you'll learn:

✅ What Infinite Scroll is

✅ How it works behind the scenes

✅ Why IntersectionObserver is the modern approach

✅ Essential React state (items, loading, hasMore)

✅ The correct way to append new data

One important thing to remember:

Infinite Scroll loads more data.
Virtualization renders fewer DOM elements.

They solve different problems—and you'll often use them together in real-world React applications.
