Last weekend I got annoyed by an issue that had been closed on the GitHub repo of the UK’s coronavirus dashboard. The issue was about the site not working at all without JavaScript and whether it could do so, and the closure comment said: “That's unfortunately impossible. The entire service has been implemented in JavaScript (not just the map).” Bit of a red rag to a bull, so I wrote a version that worked fine without JavaScript in a few hours on Sunday morning, and also used far less bandwidth/CPU/etc, stuck it up on my website, and tweeted about it.
The latest node, version 13.10, unflagged --experimental-modules and dropped most related loader warnings, so that using standard ECMAScript modules is finally possible, and without any surrounding uncertainty.
