React Native is a powerful framework that allows developers to build cross-platform mobile applications using JavaScript and React. Despite its many advantages, developers often make common mistakes when building React Native apps. Avoiding these pitfalls can help you create more efficient, maintainable, and performant applications. Here’s a rundown of some mistakes to watch out for:

1. Ignoring Performance Optimization

Problem:

Neglecting performance can lead to slow and unresponsive apps, negatively impacting the user experience.

• Avoid Inline Functions: Define functions outside render methods to prevent unnecessary re-renders.
• Optimize List Rendering: Use FlatList or SectionList instead of ScrollView for large lists to handle large datasets efficiently.
• Image Optimization: Use proper image formats and resize images to reduce load times. Consider using libraries like react-native-fast-image for better performance.

2. Poor State Management
