| invocation, in milliseconds, as a [DOMHighResTimeStamp](https://developer.mozilla.org/en-US/docs/Web/API/DOMHighResTimeStamp) |

| const [isRunning, toggleIsRunning] = useToggle(true); | ||
| useAnimationLoop(() => { | ||

In this example, it might be more useful to do something (e.g. log) the delta that is passed, to better showcase the features of this hook.

This docs (still) say delta, while the implementation (has changed?) returns the actual time.
When running an individual animationFrame, the time might be useful. When you running them in a loop, the delta is often more useful.
I don't mind also forwarding the timestamp, but I feel we should at least calculate and pass the delta.
