React Native – Introduction

React Native is an open-source framework developed by Facebook that allows developers to build mobile applications using JavaScript and React. It enables the creation of cross-platform apps for iOS and Android using the same codebase, significantly reducing development time and effort.

Key Features of React Native:

• Cross-Platform Development: Write once and deploy on both iOS and Android.
• Native Performance: React Native compiles to native code, delivering performance close to native apps.
• Hot Reloading: Developers can see changes instantly without rebuilding the app, enhancing productivity.
• Reusable Components: React Native uses a component-based architecture, allowing code reuse and modularity.
• Native Modules: You can access native device features and APIs (e.g., camera, location) through JavaScript.

How It Works:

• JavaScript Layer: The logic and UI components are written in JavaScript using React syntax.
• Native Layer: React Native components interact with native APIs through a bridge, ensuring native-like performance.

React Native has gained popularity due to its ease of use, faster development process, and the ability to create high-performance mobile apps with a shared codebase.
