The reason why the article is good to read and not just going to the site[1] it talks about is that it tells you why getting rid of JavaScript is sometimes just fine for your user base:
> ExRx makes its organizational logic plain. Its pages adopt the structure of unordered lists—uniform and sturdy...unlike elsewhere on the modern Internet, on ExRx you are never lost.

In a fitness ecosystem dominated by new- and old-school flash, from personal trainers on the hard sell to influencers with soft power, exrx.net treats me like an adult. If Instagram Reels and TikTok videos are the solicitous pusher on commission, ExRx is a librarian—or, better yet, the library itself.
