What is new in React Native New Architecture

React Native is a framework for building native mobile applications using JavaScript and the React framework. It allows you to use the same codebase for building applications for different mobile platforms, such as iOS and Android.

If a developer wants to use “Typescript” he/she should use new architecture.

In recent years, React Native has introduced a new architecture called “React Native Fabric”, which aims to improve performance, reduce the size of the application, and make the development process more efficient.

The main features of the new architecture include:

• A new runtime called Fabric, which is designed to be faster and more memory-efficient than the previous runtime.
• A new set of components called “TurboModules”, which allow developers to write code that is optimized for performance and can be easily shared across different platforms.
• A new way of managing the application state called “Async Rendering”, which allows the application to update the UI asynchronously and improve the overall performance of the app.
• From .69 on wards bundled version of Hermes is used.

Overall, the new architecture is designed to make it easier for developers to build high-performance, cross-platform mobile applications with React Native.
