With all due respect, I don't believe it is "more snappier than react".

React itself with nothing else is plenty fast. You would have to go way out of your way to see performance differences between different UI approaches, computers are just way too fast to notice whether this click resulting in the div's text changing to +1 is slow or fast, even if the implementation were crazy convoluted.

What makes react apps slow is using it badly, and having 10 other libraries getting in the picture loading fat UI elements, etc.

And frankly these would be much slower in your render everything anew approach.

This is where "react is a library, not a framework" kinda lets it have its cake and eat it too. preact is 4 kb, React + react dom is like 30 kb, but when I use it under commercial pressure to deliver it seems to climb into the megabytes. I'm working on a react native app right now that is a completely embarrassing 150 Mb. The experiment in no react, build UI from scratch every state change has stayed around 65 kb without much attention paid to bundle size, with 10 kB of that being a bunch of linear algebra and differential equation solving code and 50 kb of that a plotting library that's completely nonblocking for the rest of the app.
