You said, that React/Vue/etc. solve a specific problem: SPAs - that's not accurate. That's not the problem they solve.

According to what you said, CSS also solves the problem of making an SPA because you could "switch pages" by changing CSS class names on `body`. But if someone asked what CSS is you're not gonna answer "you use CSS to make an SPA", even though _technically_ you can use it to make an SPA.
