## What it is
React Native Reanimated is a powerful animation library by Software Mansion that lets developers create smooth, performant animations and interactions in React Native apps by running animation logic on the UI thread. It includes React Native Worklets, a companion package enabling multi-threaded JavaScript execution via worklets.

## Use cases
- animate react native components at 60/120fps
- create gesture-driven interactions in react native
- add layout animations when views enter or exit
- build sensor-based animations with gyroscope or accelerometer
- run javascript on the ui thread for smooth interactions
- animate elements between navigation screens

## When to choose
- you need smooth, high-performance animations in a React Native app
- you want gesture-driven interactions without frame drops
- you're on the React Native New Architecture (Fabric) with Reanimated 4
- you need layout, entering/exiting, or sensor-based animations

## When to avoid
- your app uses the old architecture and can't migrate (Reanimated 3 is no longer actively maintained)
- you only need trivial CSS-like transitions on web
- you're not building with React Native or Expo

## Facets
- artifact type: library
- maturity: active
- function: animation, ui-components, concurrency
- domain: mobile-development, frontend, cross-platform
- platform: -
- tags: react-native, worklets, ui-thread, gestures, layout-animations, expo, typescript, android, ios, web, javascript
