Question

JavaScript

There is such an endless, recursive animation, where the initially prescribed elements move, and then the elements begin to be generated and also move, the problem is how to remove the vibration effect, which appears most strongly on the newly generated elements.

Answer 1

everything is going smoothly enough.
Maybe fps sags for you?
Delete elements after working out so as not to keep in memory.
Put some FPS counter, I don't know if there are such counters for normal html pages.

Answer 2

1. Not setTimeout, but requestAnimationFrame
2. Delta time

Answer 3

I think it's more correct to do animation not on setTimeout, but on requestAnimationFrame
