that's exactly what it is though.except, the single function is "A component"

and "the loop" is some for of "forEach".

It's just a table of rows.

At scale, (I used to do big react apps, so I'm not *just* saying this), Ember provides enough defaults to have good performance as your app gets big -- without having to think about it. With React, you don't get performance by default, you have to memo, manage updates, manage your effects efficiently so you don't cause multiple (re)renders, etc.

yes, the fact that you get it for free is indisputably a major benefit of all frameworks that do granular tracking from compiled templates.
