Read MoreHow to wait resize end event and then perform an action using JavaScript?
When resizing a browser window, the 'resize' event fires continuously during the resize operation. This can cause performance issues if you execute heavy JavaScript code on every resize event. The solution is to wait until the resize operation ends before performing any action. The most common approach is using setTimeout() and clearTimeout() to create a debounced resize handler that only executes after the user stops resizing. Syntax let timeoutId; window.addEventListener('resize', () => { // Clear the previous timeout clearTimeout(timeoutId); // Set a ...
