I can tell you from experience that making a robust Ionic 1 app with Cordova that is performant is difficult. Cordova is not good at all.<p>We did not have chump change for developers either - I&#x27;ve numerous contributions to Angular and Ionic, and one of my former co-workers when I was there is now on the Angular team.<p>React Native is a superior abstraction, since it allows you to hook directly into native components very easily (try writing custom Cordova plugins), and keeps high level logic in JS.
