React Virtualized
React Virtualized is a React library for efficiently rendering large lists and tabular data by only rendering the items currently visible in the viewport. It uses virtualization techniques to handle thousands of rows or items without performance degradation, making it ideal for data-heavy applications. The library provides components like List, Grid, Table, and Masonry to handle various rendering scenarios.
Developers should use React Virtualized when building applications that need to display large datasets, such as data tables, long lists, or grids, where rendering all items at once would cause significant performance issues. It's particularly useful in dashboards, financial applications, or any UI dealing with extensive data, as it reduces memory usage and improves scroll performance by dynamically loading and unloading items.
