I’m sorry what?? Native code gives you access to libdispatch and concurrency. RN is single threaded. There are a myriad of processes, shared memory, optimizations, and daemons that run on your phone that coordinate better with native binaries.
Web won’t beat native on mobile phones, I’m sorry this argument has been had every single year it’s just absurd we keep arguing about it.
RN is implemented due to developer productivity at the cost of user experience. Which is fine more power to you, but understand that it doesn’t imply better UX.
The barriers to creating apps is also getting smaller (SwiftUI & Jetpack Compose).
