We often hear that React Native can hinder your performance as it's not "pure native development." Several myths tied to performance can prevent developers from using it for production apps. In this talk, I'll bust all those myths and use practical examples to discuss the performance of these real-world apps. Performance related to smooth scrolling, transitions, and using heavy native features such as camera, etc., will be covered in this talk, and we will compare how React Native performs and what we can do about it.
