Layperson's guide to React Fiber
summary
React 16 ships a complete reconciler rewrite (Fiber) that yields concrete changes: the core libs are 20% smaller, old React APIs like PropTypes and createReactClass become separate packages (deprecated warnings become errors), new return values allow arrays and scalars, and error boundaries via componentDidCatch let parts of a page fail without unmounting everything. Server rendering adds streaming with renderToNodeStream and requires hydrate on the client; async scheduling is gated behind an unstable flag and can be toggled manually.
