There's also "dynamic rendering," in which you serve Google/crawlers "similar" content to, in theory, avoid JS-related SEO issues. However, it can just be a way to do what the parent commenter dislikes: render a mini-blurb unfound on the actual page.
Shoot, even a meta description qualifies for that - thankfully Google uses them less and less.
Google will reliably index dynamic sites rendered using JS. And other search engines do the same. There's really no good reason to do this if you want to be indexed on search engines.
Agreed. Yet whether it should be done is different than whether it is done. Google was recommending it in 2018, and degraded it to a "workaround" just two years ago. Sites still do it, SaaS products still tout its benefits, and Google does not penalize sites for it. GP's gripe about SERP blurbs being missing is still very much extant and blessed by Google.
