Maximize User Experience with Infinite Scroll
What is Infinite Scroll?
Infinite Scrolling is highly trending as an interaction behavior on pages and lists. The basic functionality is that, as the user scrolls through content, more content is loaded automatically. With the popularity of social media, massive amounts of data are being consumed, Infinite Scrolling offers an efficient way to browse that ocean of information, without having to wait for pages to preload. Rather, the user enjoys a truly responsive experience, whatever device they’re using.
Demo
Getting Started
React makes the process of implementing Infinite Scroll in a Web Application fairly easy, so that’s exactly what we will be using. Set up a React Project using create-react-app or using Webpack before continuing.

We need to use useRef to store the reference to the last element for Infinite Scroll and Intersection Observer to detect if the element is visible on the screen.
Creating the App component.
Drawbacks
Infinite Scroll may lead to performance degradation, so its suggested that when using infinite scroll for large list of items (around 250+ items), you should create the following CSS class:
and add it to your items when they are not in the viewport.
