I have string in following format

<script type="text/javascript">
<!--//--><![CDATA[//><!--
jQuery.extend(Drupal.settings, { "basePath": "/", "fivestar": { "titleUser": "Your rating: ", "titleAverag.... } });//--><!]]></script>

How can I output it from jquery script as a script in a page? I have tried

var elem = $mystring;
document.body.appendChild(elem);

But it does not work. Apparently there are some characters that shoud be escaped? Thank you for help

You don't need to do that comment and CDATA stuff any more. Hasn't been needed for at least a decade. – Barmar Nov 22 '20 at 02:56
@Barmar I know but this is unfortunately the string that I have to work with. – user1031742 Nov 22 '20 at 02:59
The argument to `appendChild()` needs to be a DOM element, not an HTML string. – Barmar Nov 22 '20 at 03:02
If you have HTML you need to assign to `.innerHTML`. But that won't execute scripts. – Barmar Nov 22 '20 at 03:02
Can you use jQuery? It will execute scripts when you use its `.html()` method. – Barmar Nov 22 '20 at 03:03
@Barmar no I can not use jQuery. Javascript is my only option – user1031742 Nov 22 '20 at 03:14

Why can the script you're trying to insert using jQuery but you can't? – Barmar Nov 22 '20 at 03:15
@Barmar It is a string created elsewhere in system. I am just working with output. – user1031742 Nov 22 '20 at 03:25

@Marc That uses jQuery, they have to use vanilla JS. – Barmar Nov 22 '20 at 03:31
@Barmar, I'm the upvoter on your comment. Seems to me this person _can_ use jQuery since the code being inserted relies upon it, despite poster saying he/she cannot. But you're right; says only vanilla JS. – Marc Nov 22 '20 at 03:33
@Marc I think he's saying that this has to work in more general contexts, so maybe the script being inserted doesn't use jQuery, and jQuery isn't loaded into the page. The code shown is just an example. – Barmar Nov 22 '20 at 03:37
