## Topics Covered

### 1. Installation
```bash
npm install react-native-reanimated react-native-gesture-handler

# babel.config.js
module.exports = {
  plugins: ['react-native-reanimated/plugin'],
};
```

### 2. Reanimated Basics
```tsx
import Animated, {
  useSharedValue,
  useAnimatedStyle,
  withSpring,
} from 'react-native-reanimated';

function AnimatedBox() {
  const scale = useSharedValue(1);

  const animatedStyle = useAnimatedStyle(() => ({
    transform: [{ scale: scale.value }],
  }));

  const handlePress = () => {
    scale.value = withSpring(scale.value === 1 ? 1.5 : 1);
  };

  return (
    <Pressable onPress={handlePress}>
      <Animated.View style={[styles.box, animatedStyle]} />
    </Pressable>
  );
}
```

### 3. Gesture Handler
```tsx
import { Gesture, GestureDetector } from 'react-native-gesture-handler';

function DraggableBox() {
  const translateX = useSharedValue(0);
  const translateY = useSharedValue(0);

  const pan = Gesture.Pan()
    .onUpdate((e) => {
      translateX.value = e.translationX;
      translateY.value = e.translationY;
    })
    .onEnd(() => {
      translateX.value = withSpring(0);
      translateY.value = withSpring(0);
    });

  const style = useAnimatedStyle(() => ({
    transform: [
      { translateX: translateX.value },
      { translateY: translateY.value },
    ],
  }));

  return (
    <GestureDetector gesture={pan}>
      <Animated.View style={[styles.b
