I am not a fan of React, but there is nothing about it that exacerbated the problems OP is talking out.

The web’s layout engine is just a PITA. I also feel much more in control inside a canvas. I can do anything I want inside it.

However, DOM manipulation is not a solution to layout issues, so I am not sure the OP’s gripe is that relevant to this tutorial.

None of this has anything to do with react.

Can you please not do this here? Your post is obviously intended to be inflammatory and adds no value to the discussion.
