Is there a way to find out what version of jQuery is being used by inspecting the jQuery object? jQuery is dynamically getting added to my page and I cannot see
console.log( 'You are running jQuery version: ' + $.fn.jquery );
You can use either $().jquery; or $.fn.jquery which will return a string containing the version number, e.g. 1.6.2.
FYI, for the cases where your page is loading with other javascript libraries like mootools that are conflicting with the $ symbol, you can use jQuery instead.
For instance, jQuery.fn.jquery or jQuery().jquery would work just fine:

$()['jquery']
Invoke console.log($()) and take note about jquery object fields :

$().jquery will give you its version as a string.
You can get the version of the jquery by simply printing object.jquery, the object can be any object created by you using $.
For example: if you have created a <div> element as following
var divObj = $("div");
then by printing divObj.jquery will show you the version like 1.7.1
Basically divObj inherits all the property of $() or jQuery() i.e if you try to print jQuery.fn.jquery will also print the same version like 1.7.1
