Legend List: Optimizing for both Mobile and Web

Legend List is optimized to be as fast as possible on both mobile and web. Jay Meistrich (Founder of Legend, CTO of Bravely) shares the core optimizations behind Legend List v2, the fastest list implementation for React Native and React DOM. Many of the optimizations, like signals and minimizing renders, are shared across platforms, but there are also key differences in how lists are measured, ordered, and rendered on the web.

▪ How container recycling and minimizing renders improve performance on mobile and web

▪ Why MVCP (Maintain Visible Content Position) is critical for smooth scrolling and accurate `scrollToIndex`

▪ Differences between React Native and web implementations, from DOM reordering to GPU limits

▪ General optimization tips and tricks for making React apps scroll faster and feel more responsive
