## What it is
React components for efficiently rendering large lists, grids, and tabular data using windowing (virtualization) so only visible rows are rendered. It is a mature, widely used library with a rich set of list, table, grid, and collection components.

## Use cases
- render a list with tens of thousands of rows without lag
- display large tables in React with virtual scrolling
- build an infinite scrolling feed efficiently
- virtualize a data grid in a React dashboard
- improve rendering performance of long lists in a React app

## When to choose
- you need battle-tested virtualization components for lists, tables, or grids in React
- you want a feature-rich library with fixed-size and dynamic-size row support
- you are on an older React codebase where react-window's smaller API is insufficient

## When to avoid
- you are starting a new project and prefer the smaller, actively developed react-window by the same author
- you need virtualization outside of React
- you need cutting-edge updates or frequent new releases

## Facets

- maturity: maintenance
