If 16 ms between two events is fast enough, use
window.requestAnimationFrame().

Also see:
<https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame>

Example for the use to run an animation:
<https://arnowelzel.de/en/projects/example-for-webgl>

The only downside is, that one frame is not always exactly 16 ms as this
depends on the refresh rate of the display. On displays with 100 or 120
frames per second you only get 10 or 8+1/3 ms.
