<p>Get the speed benefits of loading jQuery (and jQuery Migrate) from a CDN while providing a fallback to the local version in the event the CDN is down. It also uses the same version as WordPress does – automagically, so you’re never out of sync.</p>
<h3>Loading jQuery from cdnjs</h3>
<p>By default, jQuery is loaded from <a href="https://developers.google.com/speed/libraries/" rel="nofollow ugc">Google</a> with jQuery Migrate being loaded from <a href="https://cdnjs.com/" rel="nofollow ugc">cdnjs</a>. If you’d like to also load jQuery from <a href="https://cdnjs.com/" rel="nofollow ugc">cdnjs</a>, add the following to <code>wp-config.php</code></p>
<pre><code>define('WPJP_USE_CDNJS', true);
</code></pre>
