How does React Native handle concurrency and asynchronous rendering?

React Native handles concurrency through JS event loop, async rendering, and concurrent-friendly architecture in React.

React Native relies on JavaScript's event loop for async tasks while React's rendering model batches updates for efficiency. With React 18 features like concurrent rendering, updates can be interruptible and prioritized. However, true concurrency depends on JS thread availability and native thread coordination. Async rendering ensures UI responsiveness even during heavy updates.
