 This method exists for [rare use cases](/blog/2018/06/07/you-probably-dont-need-derived-state.html#when-to-use-derived-state) where the state depends on changes in props over time. For example, it might be handy for implementing a `<Transition>` component that compares its previous and next children to decide which of them to animate in and out.
