I’ve been doing web development for more than 23 years. I’ve pretty much stuck to vanilla JS that entire time (though I did use jquery during the worse of the browser incompatibility years). I keep meaning to learn some of the newer libraries but never get around to it since vanilla JS does everything I want it to do and I already know it. I wonder if I would be as surprised by what libraries like Vue can do as this person is about vanilla JS.
It's an Arkanoid clone (bat and ball game) written in React, with react-three-fibre for WebGL, zustand for state management, and use-cannon for physics. The full version is about 250 lines and there's also a simplified version that weighs in at 60 lines (not including the library code obviously). It runs at a solid 60FPS on a very basic laptop.
Doing the same thing in vanilla JS, using the same libraries (or alternatives) would be a lot more work, and would end up with the exact same result. That's the point with a well written framework-driven app - when you use something like React or Vue you should be aiming to get the same end result as a vanilla JS app, but with much less effort. The cost to the user should really only be a slightly bigger download.
