I really like the idea of a Timer object. It would allow you to
separate creation from starting, allows you to pause and add other
API's to the interface. Can the constructor be used to simplify the
creation:
var t = new Timer(0, false, function() { ...});
which would start the timer immediately, as in your example. Or you
could do:
var t = new Timer(function() { ... });
...
t.startOneShot(1.76);
etc.
And you could easily add animation or media API's for synchronization:
var t = new Timer(1.76, function() { ... }); // when the timer is
triggered, it will run for 1.76 seconds
var transition = window.getTransitionForElement(element, "left");
transition.trigger(t);
...
element.style.left = "100px";
This would cause the timer to start when the left transition starts
and fire its event 1.76 seconds later.
