Understanding React Native’s Architecture for Better Performance

To optimize performance in React Native applications, it’s crucial to understand the underlying architecture. React Native’s architecture plays a significant role in how your app performs, and knowing how it works can help you make informed decisions to improve performance. In this article, we’ll take a deep dive into React Native’s architecture and explore how the bridge works and its impact on performance.

React Native Architecture Overview

React Native combines the best parts of native development with React, a best-in-class JavaScript library for building user interfaces. Its architecture comprises three main threads:

1. JavaScript Thread:

• This is where your React code runs. It handles the logic, state management, and rendering of React components.

1. Native Main Thread (UI Thread):

• This thread is responsible for handling the UI rendering and user interactions. It’s the main thread of the native application.

1. Bridge:

• The bridge facilitates communication between the JavaScript and native layers. It allows JavaScript code to call native modules and vice versa.
