A videogame is expensive to render because of several MB models, constantly moving camera, and other things.

The concept of observing elements is not even new.

The DOM does this. React does this.

Did you know CSS even invokes the GPU for certain tasks?

You guys really need more experience. I can't believe how many people apparently know nothing at all about web dev and computers.

Do you know that regular HTML and CSS use GPU all the time?

He's right - the DOM also has observers.

The difference is what is rendered, not that observers are involved and the concept of looping.

Millions use React - you want to talk about performance?

These downvoters act like native JS doesn't do the exact same thing with event listening and observing the DOM. So does React and other FE frameworks.

Philip J Fry is either being disingenuous or genuinely doesn't know that game rendering has often several MB models, is often raycasting, maintaining camera calculus, and a lot more.
