React virtualization libraries are designed to optimize the rendering of large lists or tables by only rendering the visible items in the viewport. This significantly improves performance and user experience, especially when dealing with large datasets. By reducing the number of DOM nodes rendered at any given time, these libraries minimize memory usage and improve scrolling performance, making them essential for applications that require efficient handling of extensive lists or grids.
