Yes, and 99% of the code running in a React Native app is written in Objective-C, because they are native widgets and native libraries (often just the AppKit widget or a wrapper around it). That's why it's called React Native. The JS runtime is only used to choreograph different native components. It's like a .xib or storyboard but with the ability to do logic. This code runs at user input speed so the relative performance characteristics are irrelevant. |
