Basic knowledge of iOS- en Android development necessary to develop with React Native, Ionic or NativeScript? If so or if not, why?

Hello everbody!

For college I'm doing a small research project. The goal of my research is give advice to web developers on using JavaScript frameworks to create mobile applications and help them decide which framework to use by comparing 3 popular frameworks. I decided to compare React Native, Ionic and NativeScript. I myself have only used React Native to build a mobile application. I would like to get some opinions from other developers on this matter. I want to compare the frameworks based on the following categories: developing time, performance, debugging an learning curve. Are there developers here who would be willing to write their experience with these frameworks? Or maybe some of you know a forum or other place where I can ask for some help:)
