How can I write HTML code only if JS is enabled? [duplicate]

Is there a html opposite to noscript

<noscript> makes it easy to have HTML code as a fallback if JS is disabled... but what if I want to have HTML code which is only shown when scripts are enabled? I can have a JS block which dynamically writes HTML, but is there a nicer way to do it using some regular HTML?

let's say I have a link:

<a href="test.com">This should only appear if Javascript is enabed</a>

Use a HTML element with style="display:none", set that to display:block from JavaScript.

Sample code (ugly as hell, but just to give you the idea)

<div id="hideThisFromNonJs" style="display:none">
Bla bla bla
</div>

<script type="text/javascript">
document.getElementById('hideThisFromNonJs').style.display='block';
</script>
