> One big negative for me so far is that you can't go the last mile ... if you don't already know a lot about both iOS and Android development To me it's actually one of the strongest points of RN. It's not trying to shun away the build/custom native wrapper part in favor of a magical solution; instead, it's giving you full control and full power on how you want things done. Things like Cordova have been easy and great for simple stuff, but anything that is a little bit different or needs real performance is impossible or extremely problematic to achieve. Not on RN. It can be difficult, as creating a custom native UI requires a lot of knowledge of both native platforms, and a lot of boilerplate. But the end result is superior in every way to what HTML wrappers can do. Rather than RN being a solution of one-size-fits-all like what some platforms want to be, I look at it from another angle: it still requires native mobile devs with native knowledge, but offloads 90% of the UI/business logic effort to this one universal platform. That's what most no-compromise cross-platform apps need.
