Can not get Typed.js to work

I am just trying to play around with typed.js but I can not get it to work whatsoever. I have JQuery imported before the script, I took the code almost directly off github so I am not entirely sure why this isnt working?

HTML

<div id="typed-strings">
  <p>TESTING</p>
</div>
<span id="typed"></span>

JavaScript

I just added the script tag for the file path just to show how i have it in my code. I also have script tags around the javascript code below.

<script src="apps/typed.js"></script>

var typed = new Typed('#typed', {
    stringsElement: '#typed-strings',
    smartBackspace: true
});
