What is jQuery?

jQuery is a JavaScript "framework" or "library" that makes working with JavaScript easier and more versatile. You can learn everything about it at jquery.com, but we'll hit the highlights over the next few pages. In order to use jQuery, you either have to download it and have it available within your web site structure to reference or, much more easily, simply reference the version that is hosted by google:

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>

Or this one:

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
