Lists are essential for displaying data in web applications, but handling large data sets can cause performance issues, particularly in React apps. This guide explores five techniques to improve list performance: pagination, infinite scroll, react-virtualized, react-window, and React ViewPort List. Pagination divides data into pages to reduce DOM load, while infinite scroll loads data incrementally as users scroll. React-virtualized and react-window use windowing to only render visible list portions, enhancing efficiency. React ViewPort List also employs windowing, with added support for dynamic heights and flexbox alignment. Each method has distinct advantages, and the choice depends on the specific use case and user preferences.
