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 any reference to it in my markup. If I inspect it in my browser's console, it's there.

You can use either $().jquery; or $.fn.jquery which will return a string containing the version number, e.g. 1.6.2.

Note that the version is not always precise to three levels. jQuery 1.4.0 for example prints just
1.4 for jQuery.fn.jquery

fyi, as of 2.1.4, you can use just
$.fn.jquery, no need to call the $ function now

It doesn't work when you load jquery "globaly" via webpack's 3 "ProvidePlugin" feature.

@StLia You may need to import the jQuery object...
import jQuery from jqueryFYI, 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 will give you its version as a string.

$ is a reference to the jQuery function and $() references a jQuery instance (just in case anyone wonders why)

Easy to copy/paste... :)
For older versions of jQuery
jQuery().jquery (or)
jQuery().fn.jquery
For newer versions of jQuery
$().jquery (or)
$().fn.jquery

The first syntax
jQuery().jquery worked for me with a very old version of jQuery (embedded on a legacy project): 1.10.2$()['jquery']
Invoke console.log($()) and take note about jquery object fields :
- jquery
- selector
- prevObject

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

console.log( 'You are running jQuery version: ' + $.fn.jquery );
