I knew anything I said your answer would be something in this line. You think what you wrote is amazing but it is just verbose bad abstraction. If you think the difference between 4k lines of code and separated logical modules is just a matter of fewer lines (which might not even be the case), there is nothing I can say to you but it is funny that you use this terrible code as an example. You literally wrote all DOM manipulation repetitively and inefficiently by hand. But it makes you proud! Congratulations, I guess.

I couldn't care less about JSX tho you made too many assumptions about someone that thinks the example code sucks.
