Windowing renders only visible items to prevent UI jank when dealing with large lists.

Apply list virtualization to render only the visible portion of large datasets, preventing UI jank. This technique replaces full list rendering with a windowed list to improve scroll performance and initial render speed.
List virtualization is a windowing technique that renders only the items visible in the viewport. You need it when rendering lists or grids with hundreds to thousands of items where scroll jank and slow initial render become problems.
Integrate the virtual-lists pattern in your React project by replacing a full list render with a windowed list. It supports FixedSizeList and VariableSizeList patterns from react-window to manage the visible window.
Yes, you can use react-window-infinite-loader alongside your windowing library to fetch and load more data dynamically as the user scrolls through the visible list items.
Yes, list virtualization supports VariableSizeList patterns to accommodate items with dynamic or variable heights, alongside FixedSizeList patterns for uniform items within the same windowing library.
Your React list lags because it attempts to render all items in the DOM simultaneously. List virtualization solves this by rendering only the visible portion of the dataset, significantly reducing DOM nodes and improving performance.
