What’s New in React Native’s 0.76 New Architecture

React Native 0.76 is here with a huge upgrade known as the New Architecture. This overhaul brings exciting changes and more efficient ways to build fast, responsive, and user-friendly mobile apps.

Here’s a breakdown of what this New Architecture brings and what it means for developers:

Why a New Architecture?

The original React Native structure used a JavaScript Bridge to connect JavaScript code with native code on mobile platforms (iOS and Android). This bridge was asynchronous, which could cause delays in updates, especially when many updates were needed quickly. This led to performance issues, as apps had trouble maintaining smooth frames per second (FPS) or handling real-time updates seamlessly.

The New Architecture in 0.76 addresses these issues by enabling synchronous and asynchronous updates. It’s designed to be faster and better at handling complex interactions, and it lets React Native apps act even more like native apps.

Key Components of the New Architecture

New Native Module System

• React Native now has a Native Module System that connects JavaScript with the native code directly, without using the bridge. This enables faster data transfer and synchronous…
