How to use jQuery in HTML when jQuery loads at the bottom?

according to this:

https://developer.yahoo.com/blogs/ydn/high-performance-sites-rule-6-move-scripts-bottom-7200.html

but lets imagine an MVC system. You are inside the body, and try to use $(document).ready. It wont work since jQuery is not loaded. Then what?

EDIT: so

<body>
here I need jQuery. But it wont works since its not loaded. Then how to workaround this?
</body>
<script src='jquery>

You seem to be confusing physical position of the script statement with logical availability. Any scripting that executes after jQuery is loaded has jQuery available, regardless of whether it is loaded by a tag that appears physically higher in the page than the tag that loads jQuery.
