I believe it would have been better to have Hooks as a separate library, not part of React. For the developer it is just another design pattern, not really an improvement, especially if you look at all the edge cases and issues you'll find around.

Personally I don't like the design pattern, a matter of taste. But it's very annoying now in the market to have mixed React and Hooks codebases, with all their issues..
