A string containing the jQuery version number.

.jquery()🡢 String

The .jquery property is assigned to the jQuery prototype, commonly referred to by its alias $.fn. It is a string containing the version number of jQuery, such as "1.5.0" or "1.4.4".

Determine if an object is a jQuery object

var a = { what: "A regular JS object" },
  b = $("body");

if (a.jquery) {
  // Falsy, since it's undefined
  alert("a is a jQuery object!");

if (b.jquery) {
  // Truthy, since it's a string
  alert("b is a jQuery object!");

Get the current version of jQuery running on the page

alert("You are running jQuery version: " + $.fn.jquery);
