Are you seriously confused at the difference between JavaScript performance in the browser and native code?

Yes, native code by definition runs faster than javascript in the browser. Orders of magnitude faster.

Databinding in the browser also wasn't designed in, there's no direct support. AngularJS is a wrapper around a ton of functionality.

If an API is built to support that natively, it will fly. Period.

It's also something iOS and OS X have had FOR YEARS. no one can complain about those being poor performers.

I don't think anything like Android's Data Bindings exists first party on iOS. Cocoa Bindings are only for OS X.
