## Ship motion that survives real users

| Lesson | Focus |
| --- | --- |
| [Utils](/learn/gsap-react/production/utils) | clamp, mapRange, quickTo, distribute |
| [Performance](/learn/gsap-react/production/performance) | GPU props, stagger, cleanup |
| [Craft](/learn/gsap-react/production/craft) | Frequency table, anti-patterns |

```tsx
// Kill stale ScrollTriggers on route change (SPA)
ScrollTrigger.getAll().forEach(t => t.kill());
```

In React, prefer **`useGSAP`** so context revert handles most cleanup.
