What's the difference between setting the Animated Value in the onPanResponderMove method via "Animated.Event" and "setValue"?

Question

If you want to drag and drop an element with PanResponder, you could pass the values of the movement to the onPanResponderMove method in two ways:

1. With Animated.Event

onPanResponderMove: Animated.event([
    null,
    { dx: this.state.pan.x, dy: this.state.pan.y }
]),

2. With .setValue

onPanResponderMove: (evt, gesture) => {
    this.state.pan.setValue({x: gesture.dx, y: gesture.dy})
},

Both appear to do the same thing in my tests. What is the difference?
