    Capture values using the lifecycle hook getSnapshotBeforeUpdate in React 16.3

    getSnapshotBeforeUpdate is a lifecycle hook that was introduced with React 16.3. It is invoked right before the most recently rendered output is committed and the value returned by it will be passed as a third parameter to componentDidUpdate. It enables your component to capture current values for example a scroll position before they are potentially changed.
