What are the best practices for using key extractor in React Native?
When using key extractor in React Native, ensure that each key is unique to avoid rendering issues. Use stable identifiers.
Can you give an example of a key extractor implementation?
Sure! You can implement it like this: keyExtractor={(item) => item.id.toString()} where id is a unique identifier.
What happens if I don't use a key extractor?
Not using a key extractor can lead to performance issues and incorrect item rendering in lists.
Are there any performance tips for optimizing lists in React Native?
Yes! Use FlatList with proper key extractors, avoid inline functions, and implement pagination for large datasets.
