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:
Javascript doesn't "just work". It's a language originally designed to glue actions to html elements and it is fundamentally broken in ways that will be never be fixed. Weird syntax, weird type coercion, horrible base types & functions, surprises galore. Even Typescript, which is basically a precompiler, is just JS with some type checking. The only reason anyone uses either is because it is ubiquitous - people have to use it.
