An example of how to interpolate animation properties based on a base Animated.Value

ReactNativeInterpolation.js

let baselineAnimationValue = new Animated.Value(0);
let titleXPosition = new Animated.Value(0);
let titleOpacity = new Animated.Value(0);

// our baseline animation, going from 0 to 1
function runBaselineAnimation() {
  Animated.timing(this.state.baselineAnimationValue, {
          toValue: 1,
          duration: 2000, // 2 seconds
        }).start();
}
// move the title up as the animation runs
function titleYPosition() {
	return baselineAnimatedValue.interpolate({
      inputRange: [0.0, 1.0],
      outputRange: [0, -42], // animated between 0 and -42
      extrapolate: 'clamp',
    }
}
// fade the title as the animation runs
function opacity() {
	return baselineAnimatedValue.interpolate({
      inputRange: [0.0, 1.0],
      outputRange: [1.0, 0.5], // animate between 1 and 0.5
      extrapolate: 'clamp',
    }
}

<Title style={{opacity: titleOpacity(), transform: [{ translateY: titleYPosition() }] />
