- 18 App launch is slow, how do we measure what's making it slow?
- 19 When starting a new project for state management, do we still need to use Redux?
- 20 What are your thought on React Native Flipper performance monitor?
- 21 Is it a good practice to wrap your component with React.memo with custom comparer function?
- 22 How to improve performance of large lists?
- 23 Is the app’s entry point an ideal place for initial app setup operations setup error reporting, notifications, global listeners i Are sagas better suited for this?
