Hi all!

Just started using Elm and I'm really liking it.

One question I had is whether it is possible to integrate a library like 
KaTeX that actually modifies the content of a DOM element that is 
controlled by Elm.

If so how would I do that? React/Mithril have ways of interrupting the 
rendering lifecycle to squeeze in your own behavior, but how does Elm allow 
for that?

Another simple way to do it is to render a script tag, like:

<div id="katex">
<script> KaTeX.render('...', document.getElementById('katex')) </script>

I can render a script element, but I need to force elm to re-render the 
script tag each time, and for that, React allows you to put a key 
attribute. Is there something similar in Elm?

There are a lot of other widget-like js libraries that I wanted to include 
on my webpage, like musicalabc (abcjs) or mermaid.js, or highlight.js, etc.

Any ideas? Thanks!

Vishesh
