Postponing Code Running In JavaScript
Creating user interfaces in JavaScript can sometimes lead to a problem, especially when the interface used AJAX to load data from the server. As many actions will be event driven by the user you can find that when a user triggers lots of events all at once the browser will send out lots of AJAX requests all at once. This can easily cause bandwidth issues but can also lead to the user getting confused while they patiently await the browser to settle down and let them get on with things.
