React useOnWindowResize Hook
Difficulty: Beginner | Time: 5 minutes
In this lab, we will learn how to create a custom React Hook called useOnWindowResize that will execute a callback whenever the window is resized. We will use the useRef() and useEffect() hooks to listen to the 'resize' event of the Window global object and clean up when the component unmounts. This Hook can be useful for creating responsive web applications that need to adjust to different screen sizes.
