## What it is
A tiny (~600 bytes) JavaScript library that eliminates layout thrashing by batching DOM measurement and mutation tasks. It queues reads and writes and flushes them in order at the next animation frame via requestAnimationFrame, avoiding unnecessary reflows.

## Use cases
- fix layout thrashing in my web app
- batch DOM reads and writes to avoid reflows
- improve scroll and animation performance
- coordinate DOM access across multiple modules
- speed up JavaScript-driven animations

## When to choose
- your app performs interleaved DOM reads and writes causing jank
- you want a tiny, dependency-free performance fix
- multiple modules or third-party scripts need harmonized DOM access

## When to avoid
- you use a framework with its own batching (e.g. React, Vue) and rarely touch the DOM directly
- you need server-side DOM manipulation
- you require an actively developed library with recent features
