An text file with a <script> block and nothing else, containing a console log, is all you need. You already have all the boilerplate to run it in any computer. No extra dependencies, no installing anything. Literally just a notes editor app. This is a valid HTML file:
<script>
console.log("Hello World")
</script>
Youtube hooks me with really interesting shorts and within a couple shorts it always derails to the worst brain melting garbage. I really don’t get it.
