Hey Coders,
Welcome to the eight edition of our newsletter to make you a better frontend developer. Today’s challenge is about scrolling, that you guys probably doing too much 😉
Here is the description of the challenge:
The component implements infinite scrolling functionality, where additional content is dynamically loaded as the user scrolls down the page. It leverages React hooks such as useState, useEffect, and useCallback to manage state and handle scrolling behavior efficiently.
Initial Data Load: The component starts with no items and loads data on initial render.
Scroll Detection: It listens for the window’s scroll event and detects when the user reaches the bottom of the page.
Lazy Loading: When the bottom is reached, a timeout simulates a network request, loading more items after a delay (1 second).
Loading Indicator: While new items are being fetched, a loading message is displayed to inform the user.
Performance Optimization: The useCallback hook ensures that the loadMoreItems function doesn't get unnecessarily recreated on every render.
The dummy data is generated with a function (generateDummyData) that returns an array of 20 items for each load. Items are appended to the existing list, creating a seamless scroll experience.

That’s all folks. See you next week!
