What specific section or headline is this issue about?
First two code examples
What information was incorrect, unhelpful, or incomplete?
The calls to
window.requestAnimationFrame(draw);
in the first sample and
window.requestAnimationFrame(clock);
in the second sample inconsistently use the window reference when using DOM API's
What did you expect to see?
I expected not to see the reference to window
requestAnimationFrame(draw);
and
requestAnimationFrame(clock);
in the second sample
Do you have any supporting links, references, or citations?
The last sample is consistent with the implied use of window.
It shows consistent reference via implied window as follows requestAnimationFrame(anim)
As do all samples showing implied window reference for document rather than window.document
Do you have anything more you want to share?
Maybe a second issue? The first sample uses Date to get a time to used to animate content rather than use the time parameter (not defined in the sample) passed to the requestAnimationFrame callback.
