React Vs. React Native: How to choose the right technology?

React vs. react native

The confusion between React and React Native primarily stems from their names and shared origin. Facebook introduced both; both employ component-based architecture, and both use JavaScript. Those unfamiliar with their difference often end up comparing React vs. react native, like react native vs. Flutter, to choose the right tech stack for their project.  Their name gives the impression that they are the same or at least very similar.

React JS:

React, originally termed “React.js,” is an open-source JavaScript library for building user interfaces. It was developed by Jordan Walke, a software engineer at Facebook, and was first introduced in 2011 at Facebook’s newsfeed feature.

React gained rapid popularity due to its unique approach of breaking UIs into reusable components and its virtual DOM implementation, which optimized rendering performance. The idea was to create fast, scalable, and simple user interfaces. React was then open-sourced at JSConf US in May 2013.

React Native:

Inspired by React’s architecture and potential, Facebook introduced React Native in 2015 during their F8 conference. React Native leverages the same design as React, letting developers use a similar component-based structure and React native IDEs to create native applications for both iOS and Android. 

Instead of targeting the browser, React Native targets mobile platforms, allowing JavaScript to be executed on the device and interact with native APIs. React Native allows developers to write native apps using a familiar web development paradigm.

React Vs. React native: Differences

1. Platform:

  • React: React is primarily used for building web applications. It targets web browsers as its runtime environment, rendering HTML and CSS for the web.
  • React Native: React Native is designed for building mobile applications that run on iOS, Android, and potentially other platforms. It compiles to native code and runs on mobile devices, allowing for native mobile app development.

2. Components:

  • React: React components are built using HTML, CSS, and JavaScript (JSX). Developers use JSX to define the structure and appearance of components, which are rendered in web browsers.
  • React Native: React Native components are composed of native UI elements provided by the respective mobile platforms. Developers use React Native components like <View>, <Text>, and <Image> that map to native UI elements on iOS and Android.

3. Styling:

  • React: Web developers use CSS for styling React components. They have access to styling frameworks like Bootstrap and Sass to manage design and layout.
  • React Native: React Native does not use CSS. Instead, it employs a JavaScript-based styling approach using a style object resembling inline styles. This approach ensures consistency with native UI guidelines.

4. Development Environment:

  • React: Web development with React typically occurs in standard web development environments using browsers, text editors, and tools like Chrome DevTools.
  • React Native: Developing with React Native often involves setting up platform-specific development environments. For iOS development, macOS and Xcode are required, while Android development requires Android Studio and the Android SDK.

5. Performance:

  • React: React web apps rely on the performance of the user’s web browser for rendering. Performance can vary depending on the browser and device.
  • React Native: React Native apps deliver native-like performance because they utilize native UI components. They can access device-specific optimizations and GPU acceleration, resulting in smooth and responsive user experiences.

6. Deployment and Distribution:
