## What it is
FlashList is a fast, performant list component library for React Native that replaces FlatList using view recycling to eliminate blank cells and reduce memory usage. Version 2 is a JS-only solution built for React Native's new architecture, requiring no size estimates and supporting Masonry layouts.

## Use cases
- render long scrolling lists in React Native without blank cells
- replace FlatList with a faster drop-in list component
- build Pinterest-style masonry grids in React Native
- improve scrolling performance on low-end Android devices
- display mixed item types efficiently with recycling pools
- keep list content position stable when prepending items

## When to choose
- your React Native app has long or complex lists with frame drops or blank cells
- you want a near drop-in FlatList replacement with better performance
- you target low-end Android devices where FlatList struggles
- you need masonry or variable-height layouts in a mobile list

## When to avoid
- your app runs on React Native's old architecture (use FlashList v1 instead)
- you are not building with React Native
- your lists are very short and FlatList performance is already sufficient
