What Andrew said confused me. Why is an anonymous function not desirable for the clock application exactly?

Also, why does Andrew call tickClock() in the original code, and what does he mean by "can't wait for the first setInterval call"?:

setInterval(tickClock, 1000);

That is confusing as well.

The callback passed to "setInterval" will not run until the first interval has elapsed. So if you "can't wait" (meaning you want an immediate update), you call the function ("tickClock" in this case) directly one time.

Oh ok, is that because of the 1000ms that the first tickClock() would have to wait? I get it now!
