FlatList vs SectionList in React Native

What's the difference between FlatList and SectionList in React Native?

FlatList is used for rendering a simple list of items, while SectionList is for rendering sections of items, each with a header.

When should I use SectionList instead of FlatList?

Use SectionList when you need to group items into sections, like categories, with headers for better organization.

Can I use FlatList for a grouped list?

Yes, but it won't have section headers. For grouped lists with headers, SectionList is the better choice.

Are there performance differences between the two?

Yes, SectionList can be more complex and may have a slight performance overhead due to managing sections, but it’s optimized for that use case.
