Public service announcement!

Some time ago, I may have advised people here to use javascript like:

(function () {
  // some code here
})();

to hide variables and avoid them leaking into the global namespace.
I since realise this is no longer the best way to do it. If you're working on a project that uses jQuery (which Quest does), you should instead be using:

$(function () {
  // some code here
});

this does pretty much the same thing; but may delay the code slightly until the page has finished loading (a bit like Quest's on ready block, but not quite)
