Simple explanation: they screwed up. :)

Looks like they included and escaped the <div> and <textarea> tags
intended to display the example JS code.

Note that the second and later code listings are intended to be included
in separate .js files (e.g. "...we can create the JavaScript files that
we are including. The first file is...").

<script> is a HTML tag. It is used in HTML markup (and nowhere else) to
include script code in the page. It can do this in one of two ways:

1. as the content of the tag

2. from a separate file (using <script src="...">)

A .js file should contain nothing but JavaScript code. <script> tags are
not scripting code. I would expect using <script> in a .js or other
script file to cause errors, and would consider it a bug if it did not.

I suggest you contact the site's owners and ask them to correct the errors.

cheers
