# React Component Performance

Chase down the reason a component feels slow

## What this does

A part of your React interface feels slow: it lags when you type, a long list stutters, something re-renders over and over. This looks at the component, works out where the time goes, and improves it. Reach for it when the app works correctly but does not feel right.

### Top 3 things it does for you

- Find out why this component renders slowly
- Cut down needless re-renders
- Fix a list that stutters when it scrolls

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## Questions

### Is React Component Performance safe to install?

AIR scanned this exact version of React Component Performance and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 05ba982bfeb0, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/react-component-performance.

### How do I install React Component Performance?

Open https://airmarket.ai/app/react-component-performance on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/dimillian/skills/tree/05ba982bfeb0d77d3c97d4542b0ee15034d05f84/react-component-performance.
