Learn Once; Write Anywhere
Download as ODP, PDF1 like422 views
React Native allows developers to write mobile apps using JavaScript and React that run natively on iOS and Android, avoiding the need to learn and use Objective-C, Swift, or Android Java. It addresses issues with single-threaded JavaScript by using a main thread with asynchronous and batched updates to improve app performance. While native languages are established, React Native enables writing code once that runs on both platforms and lowers the barrier to mobile development.
