Run latest version of jQuery from console.

jQueryLatest.js

/**
 * If you're working on a project that doesn't have jQuery or is using an old
 * version, you can take advantage of the latest jQuery for debugging and
 * troubleshooting from he console! 
 *
 * Enter the following code into the console following the instructions in the
 * comments. Once you're done, you should be able to use $l alongside
 * any version of jQuery that already exists.
 * 
 * I put this together with help from these posts:

// Load the latest version of jQuery.
var jq = document.createElement('script');
jq.src = "http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js";
document.getElementsByTagName('head')[0].appendChild(jq);

// Wait a bit to make sure it's loaded. Then run:
var $l = $.noConflict(false);
