Cons
Con Weak documentation
The documentation for the app framework is fairly basic, with a limited number of descriptions/explanations given.
Con Nativescript + Angular apps for Android tend to have long startup times.
It's very difficult to have acceptable startup times with NS+Angular in Android. It's not uncommon to see apps taking 6 sec or more to start AFTER having been optimized with Webpack (mandatory!). The same app in iOS takes only 2-3 sec. Also, this seems to happen only with the NS+Angular flavour. People using plain NS (without Angular) don't seem to have the issue.
