JS frameworks are very much in the "full-blown app" category.

As an example, the "react" is just a view layer is a purest pov, to me (or whatever the given framework in question is). Nextjs, Vercel, supabase, lovable, and so on down the line all empower millions of people to ship full-blown apps. We might get carried away with which specific layer is in question, but it doesn't matter if they're always used together to ship millions of (in)secure apps.
