Vidly: 18- Sorting- Moving Responsibility

Hi! In the Mastering React course, in the section on pagination there is a video where Mosh explains how it is necessary to move responsibility from a parent component to a child, specifically the information on how to sort the movieList component by raising an event to the parent, where the event is handled without containing all the logic. I understand it is important to make components as independent as possible, but don’t quite understand why in this specific case, since it’s unlikely that the Movie component (parent) would be separated from the MovieList (child) anyways.
