Cons
Con A bit confusing for beginners
The official React documentation does not do a good job in explaining the fundamental concepts as easily as possible to a beginner. In fact, it sometimes skips the fundamentals altogether. This is probably because the documentation was written by engineers who have worked on React and that never had to learn it themselves.
