I'm glad I learned React during the time when React.createClass was the only way. It was simple and intuitive. At that time the docs included a very lengthy discussion of what should be put inside the class and what should be passed via props. It was very helpful when it comes to teaching newcomers to architect their app. It also carried over the years of intuition by the typical dev working with OOP. Much better than the current trend of using hooks for everything.
