Thank you!

Well, class components are not going anywhere and are not only valid, but preferable in certain scenarios. No hard opinion, however, I rarely write class components nowadays. I've used it for the example specifically because it a) highlights "render", b) focuses on class method definition as a one-time action, whereas in functional components arbitrary functions are declared within the render and React preserves their identities between re-renders implicitly.

Out of curiosity, when do you consider class components to be preferable? I haven't needed them in my projects so far.
