Browser throwing error on included javascript

This should be trivial - trying to include a javascript library in a blog post. The trouble seems to be with

<div id="box" class=..."></div>
<script type="text/javascript">
 var board = JXG.JSXGraph.initBoard('box', ... )
 </script>

Now I know that JXG is being loaded properly, but the single quotes around 'box' in the third line are turned into

&lsquo;box&rsquo;

in the HTML page generated by Hugo, and the browser (both Chrome and Firefox) complains about an illegal character. I would have thought that the <script type="text/javascript"> would ensure that all commands in the script would be fed without change into the javascript library for processing, but it seems that even within this script, some string-to-HTML conversion is being done.

How can I ensure that all commands inside <script> ... </script> are fed to javascript precisely as written?

(Note to moderators: this is very similar to a question I’ve asked in another topic; I’m creating a new topic in the hope of finding some more people who might be managing this issue themselves.)

Thank you very much - but an even easier way was to wrap the whole box and dice in a single <div></div> tags:

<div id="box" class="jxgbox" style="width:500px; height:500px;">
<script type="text/javascript">
 var board = JXG.JSXGraph.initBoard('box', {boundingbox: [-10, 10, 10, -10],axis:true});
 var p = board.create('point',[1,1]);
</script>
</div>
