useAnimatedRef
This hook provides extended functionality of a standard ref. You can assign it to some component like <View ref={ animatedRef } /> and then access the target component via animatedRef.current. Besides, on the UI thread animated reference also contains the view tag of the target. It can be accessed like this: const viewTag = animatedRef(). This comes handy when using native methods like scrollTo and measure.
Example
const Comp = () => {
  const aref = useAnimatedRef()
  useDerivedValue(() => {
    const viewTag = aref();
    // ...
  })
  const componentRef = aref.current
  // ...
  return <View ref={aref} />;
}
