jQuery CDN Fallback

Using a CDN to load jQuery most likely will speed up your website. Moreover, your visitor may already have it cached from a previous visit to another site using the same CDN. But what if the CDN goes down for some reason? The best solution would be to use the CDN version of jQuery first, and if it fails, load the local copy.

Here is a fallback technique:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script>window.jQuery || document.write('<script src="path_to_your_js_lib/jquery.js"></script>')</script>
