javascript code is not running, Error: Can't find variable $

I'm just trying to hide a paragraph, this is the code: $(".test").hide();

The console error is showing: Can't find variable $.

And this is the script tag in the html file: <script src="js/script.js"></script> I placed it just above the body closing tag (</body>) Help with this please

Actually, if you are doing something on your own, it could be as simple as not linking a jquery file.

You would need to download jquery file from

https://jquery.com/download/

or put this above your other script file at the bottom above the body tag

<script src="https://code.jquery.com/jquery-1.11.0.min.js" type="text/javascript" charset="utf-8"></script>
