Regardless, you missed the point. Which was that, frameworks come and go. The DOM and other APIs implemented by the browser, on the other hand, are here to stay. Very few things built into the browser have been taken away (such as blink and frameset).

Right. And that makes failures and perf issues hard to track down.

If you know how to program using APIs and components built into the browser, that is easier at this point.
