How React Native Works
React Native operates by utilizing a concept called the “virtual DOM,” similar to React for web development. In this framework, developers write code in JavaScript using React and React Native. When the app is launched, the JavaScript code runs on a dedicated thread known as the “JS runtime.”
This JavaScript code communicates with native modules through a bridge layer. These native modules interpret the JavaScript instructions and execute platform-specific code. They also handle rendering UI components on the device’s screen using native APIs provided by the operating system.
As updates are sent from the JavaScript code, the UI components receive them and re-render accordingly. This ensures that the app’s logic and visual elements stay synchronized. Overall, React Native facilitates seamless interaction between JavaScript-based logic and native platform capabilities, enabling the development of cross-platform mobile apps with a native look and feel.
