How does Animated.Event work in React Native?

Question

I\'m I understanding it correctly ? Does this two set of code meant the same thing ?Does it have any difference in performance or reliability ?

Answer 1

Yes there is a difference in semantic

The first one i.e the above Animated.event returns a function that sets the scrollview's nativeEvent.contentOffset.y to your current scrollY state which I assume is animated.

The other code just sets scrollY to your scrollView's e.nativeEvent.contentOffset.y and causes a rerender to your component
