Oh I'm sorry, I was waiting for you to name a more successful cross platform development language and framework?

Oh, you're listing Java, and Xamarin, and otherwise rewriting the same app 4 times? Cool beans bro. Great development choices you've made.

All filled with thousands of dependencies badly managed through npm to overcome the lack of a standard library actually useful for backend stuff.

Bruh, this is the dumbest fucking complaint. "Open source language relies on open source packages, OMG WHAT?!?!!"

Please do go ahead and show me the OOTB OAuth library that comes with your backend language of choice, or kindly stfu about everything you need being provided by the language and not by third party libraries.
