Improving Scroll Event Performance: Efficient Handling Techniques
Optimize scroll events to prevent performance issues! Use a dedicated scroll entity, queue, throttle (delay) or debounce (await) scroll events to improve efficiency and reduce CPU usage.
Not properly handling these scroll events can lead to serious performance issues: Partially by blocking the DOM rendering process. A huge number of registered events increases CPU usage, causing reduced battery life of mobile devices. If you rely on scroll events for heavier computations, you will inevitably cause memory leaks to occur and degrade your web app further The practices introduced in this post are especially relevant for heavily interactive websites. They'll help you make your scroll events more efficient in a central space. Let's dive in. TL:DR You can find the Code Sandbo...
