@soviut @slightlyoff It is not true that SPAs are all long-running applications, not at all. Maybe that was the original goal, but it is considerably wider than that now. Definition: a site is an "SPA" if clicking a link doesn't work without JS. (Having the link not even be there to be clicked without JS also counts.) By this, a lot of newspapers are; most restaurant sites; most promotional sites: how are these things "sites I keep open for a long period"? All I want is to see the opening hours!
