Why are we rendering 100k items in React instead of paginating? Let's benchmark the DOM memory footprint.
Pagination requires network roundtrips. With @tanstack/react-virtual, we only maintain 15 DOM nodes in the viewport while keeping the full 100k state local in memory/IndexedDB.
Exactly. Plus, with BroadcastChannel synchronization, cross-tab mutations sync in sub-millisecond local IPC time without hitting the server.
