The point is to get the first DOM node, so you'd still need to do [0], which
would still throw an error if there was no match. If you're not certain that
there'll be a match, maybe something like this would be safer:
var $foo = $('#foo');
if($foo.length > 0) {
var foo = $foo[0];
} else {
// no foo
}
I use $ to prefix variables that point to a jQuery object as a convention to
remind myself that it's a jQuery object.
