Coding Session: React Native Practice

on YouTube ↗22m

" summary

Shows building a React Native app from a TypeScript template, launching emulators, and using Fast Refresh for live edits. Demonstrates a scrollable demo list of 2–5k items implemented with FlatList virtualization, explores reducing the virtualization window (which creates white gaps), inspects the Yoga layout engine and the Hermes runtime (which precompiles JS at build to skip parse/compile on startup), and explains performance techniques like PureComponent/React.memo and static-item optimizations with measured caveats.
