What is rn?

RN, short for React Native, is a popular framework developed by Facebook (now Meta) for building native mobile applications using JavaScript and React. It allows developers to write code once and deploy it on both iOS and Android platforms, significantly reducing development time and cost.

Here's a breakdown of important aspects:

• Cross-Platform Development: React Native is primarily used for creating applications that work on multiple operating systems from a single codebase. This is a key advantage, compared to native development which requires separate codebases for each platform.

• JavaScript and React: JavaScript and the React library are at the heart of React Native. If you already know these technologies, you can quickly start building mobile apps.

• Native UI Components: Unlike hybrid apps, React Native uses native UI components for each platform. This means your app will look and feel like a genuine native app on both iOS and Android, offering a superior user experience.

• Hot Reloading: Hot Reloading lets you see changes to your code almost instantly without having to rebuild the entire application. This greatly speeds up the development process.

• Large Community and Ecosystem: Community Support and access to a large ecosystem of third-party libraries and components makes it easier to build complex features and functionalities.

• Performance Considerations: While React Native offers near-native performance, it's important to consider optimization strategies for performance-critical sections of your app. Performance Optimization is a crucial aspect to consider.
