Virtual Scrolling
Virtual scrolling is a performance optimization technique used in web and application development to efficiently render large lists or datasets by only displaying the visible items on screen. It dynamically loads and unloads content as the user scrolls, reducing memory usage and improving responsiveness. This approach is commonly implemented in UI frameworks and libraries to handle extensive data without overwhelming the browser or device.
Developers should use virtual scrolling when building applications that display large lists, tables, or grids, such as data dashboards, social media feeds, or e-commerce product listings, to prevent performance bottlenecks like slow rendering and high memory consumption. It is essential for creating smooth user experiences on both web and mobile platforms, especially when dealing with thousands of items, as it minimizes DOM manipulation and enhances scroll performance.
