Concise and simple functional components are often desirable. But class components and OOP allow you to make components that are complex yet generic and reusable. Example from real experience: I had an `InfinityScroller` functional component. The `loadMoreItems` prop signature was a function with ten arguments because different usages require different state data when deciding what to load. I converted the component to class based. `loadMoreItems` became an abstract method. No more overly complicated type signature because I can just access and update `this.state`.
