These libraries are designed to efficiently render large lists of data in React applications, enhancing user experience by loading content dynamically as the user scrolls. They help manage performance issues associated with rendering extensive datasets by implementing virtualization techniques, which only render items that are currently visible in the viewport. This approach minimizes the number of DOM nodes created, leading to improved performance and responsiveness in applications that deal with large datasets.
