How to append script, link, and meta tags onto head using JavaScript?

Question

I got output like below, how to append whole into the head tag using JavaScript?

<meta name="generator" content="Joomla! - Open Source Content Management" />
<title></title>
<link rel="stylesheet" href="templates/css/template.css" />
<link rel="stylesheet" href="templates/css/templatee.css" />
<style type="text/css">
    <![CDATA[
        BODY {background: #00ff00;color: rgb(0,0,255);}
    ]]>
</style>

Notice, that appending some meta tags after the head has been parsed is not useful, they are simply ignored. — Teemu

The title of your question says you're appending a script tag, but your example contains no script tag. — user663031

head is guaranteed to be loaded and parsed before body, forking head afterwards breaks the default behavior. So, basicly you shouldn't do this. If you need dynamic head, create it on server-side. Rather this sounds like an XY-problem, what is the actual purpose of re-building the head? — Teemu

You can try this:

document.querySelector('head').innerHTML = "insert your code here"

Why not just document.head? Anyway, this will obliterate whatever content the head element used to contain.
