How to determine and print jQuery version?

Is there a jQuery function that returns the version of jQuery that is currently loaded?

Alert is good, but if you want to actually print the jquery version... 

<script>
document.write($.fn.jquery);
</script>

You can use this:

$.fn.jquery
//or if you're using .noConflict():
jQuery.fn.jquery

It's updated automatically when jQuery is built, defined here: http://github.com/jquery/jquery/blob/master/src/core.js#L174

Make sure to use $.fn.property for properties that don't depend on an object, no reason to create an unneeded jquery object with $().property unless you intend to use it :)

$().jquery;

This will return a string containing the jQuery version

I'm not sure how many versions of jQuery this exists in, but a jQuery object has a jquery property that stores the version.

alert( $().jquery );

Will alert 1.4.2 if you're using that version.
