Agreed, but as I mentioned in my edits of the comment, you’ll likely end up needing to solve all these problems in vanilla JS as well. So it’s really a question of picking your poison.

Also, many of the concepts you need to learn for proficient react development are auxiliary to react and could be applied to vanilla JS or really any UI framework. Any UI is fundamentally a state machine, and solutions to implementing it all require state management and clean separation of the presentation and data layers.
