I like how he concludes "The practices and principles described on this site are still considered niche in the industry as a whole". Like he's the only one out there who knows about the details/summary tags, or who uses static HTML documents instead of React.
The details tag is a mainstay of the "You don't need JS" genre. Every time I see it mentioned in one of these, it's always presented like it's new, unknown, and maybe a bit secretive. "OoOOoOo, bet you would write a component for this right? Well aren't you feeling silly??"
I think it's showed up on every app I've worked on for the past 5 years.
Are the practices that the author wrote about common? Judging from comments, frameworks are more common than plain JS, and half of those using frameworks don't fully understand what's possible without one.
I think it's fair to say a practice is niche if you don't see it anywhere and appear to be one of the few talking about it.
