`document.currentScript` is more useful than I thought.

Huh. Today I learned (from Alex MacArthur): you can access the current <script> element from a script (if it’s not type="module") with document.currentScript. Meaning you can put configuration data as attributes on it and pluck them off and use them. Like:

<h1 id="setMePlease"></h1>

<script data-some-value="foo">
  const scriptData = document.currentScript.dataset;
  setMePlease.textContent = scriptData.someValue;
</script>Code language: HTML, XML (xml)
