setTimeout(function() {
  console.log("2 seconds");
}, 2000);

setTimeout(function() {
  console.log("now??");
}, 0);

console.log("now");

In case I miss you it goes "now" "now??" and then "2 seconds". I'm guessing that even though the setTimeout function is set to wait 0 seconds, you still have to wait for javascript to push setTimout to the stack, then the anonymous function to the stack. Then it would have to pop the anonymous function off, and the calling function after that - which have to happen slower than the console.log function that prints "now"

Or does the callback function to setTimeout only get pushed onto and popped from the stack when setTimeout is called?
