setTimeout() require qualification

The two javascript functions above are very useful. The first one executes something after a set delay, and the second executes something at regular intervals. The syntax is very similar.

var time = 2000; // 2 seconds
window.setTimeout(function() { alert('Yay!'); }, time);
window.setInterval(function() { alert('Woo!'); }, time);

Unfortunately, they weren’t working for me earlier. It turns out I wasn’t fully-qualifying them. Specifically, I was calling setTimeout() rather than window.setTimeout(). The latter works.

Most examples use the abbreviated form, which consistently doesn’t work for me.
