## What it is
A WICG exploration of a built-in `<virtual-scroller>` web platform element that renders only visible items from very large lists while preserving accessibility, find-in-page, and SEO. The project is no longer actively developed; work moved to the display-locking primitives.

## Use cases
- render huge lists in the browser without performance loss
- virtualize long feeds like social media timelines
- keep virtualized content accessible and crawlable
- implement infinite scrolling lists on the web
- avoid shipping a third-party virtualization library

## When to choose
- you want to study the design of a browser-native virtual scroller
- you need a reference for how virtualization could integrate with accessibility and SEO

## When to avoid
- you need a maintained virtualization solution for production
- you want a ready-to-use component today - use React Virtualized or similar instead
- you expect new features or bug fixes

## Facets
- artifact type: library

- function: ui-components, frontend-framework
- domain: web-development, frontend, performance
