In this comprehensive tutorial, you'll learn how to implement infinite scrolling in React using Intersection Observer API under 9 minutes. You might have came across infinite scrolling in social media applications, since it's very commonly used, but its setup can be daunting. This video aims to simplify the process by providing a step-by-step guide on how to set up infinite scrolling using React and Intersection Observer. Essentially, infinite scrolling is a sophisticated form of pagination that eliminates the need for the user to click a button to load more content. Instead, we replace the button with a scroll event. However, setting up a JavaScript event on scroll can be inefficient. To address this, we will leverage the powerful Intersection Observer API, which allows us to efficiently check whether the last element of our content is loaded, resulting in a smoother and more seamless user interface.

🧠 Concepts Covered:
- How to make custom React hooks
- useEffect, useState, useRef, useCallback hooks
- What is Intersection Observer API and its use-cases
- Using Intersection Observer API with React JS
- How to use React Query's Infinite Query hook to implement infinite scroll
