I disagree. This seems to strike a good balance between ease of use and power. It offers a visual tool for layout while still placing the code front and center.
so i need to learn IOS and Android development to learn what's going on behind the scenes as well? Ideally right? But that's definitely not a prerequisite of building RN apps. Abstractions are great if its done well..
Why the bad karma? Look, there are people that like Emacs (like me) and there are people, especially designers, that like drag-and-drop. Even if all it accomplishes is rapid prototyping, there is great value in closing the gap between UXPin and Emacs.
