What is React.JS?

React.JS is a JavaScript library supporting the front-end web and the server-side operations for the development of web apps and web user interfaces and user interface (UI) components. Created by Facebook, React JS on meant primarily for visualization and rendering of user-friendly UI, and takes care of the application view within a Model-View-Controller. React.JS has a large community of independent developers and programmers who are constantly working at building and maintaining a rich and high-performing library of JavaScript tools and frameworks. As the popularity and developer community of open-sourced React.JS grew further, React Native was born in 2015.

What is React Native?

React Native, on the other hand, is primarily a framework for mobile apps and is today the most widely used JavaScript frameworks for cross-platform mobile app development. React Native compiles to native app components that lets app developers build native mobile apps for all kinds of the mobile OS using JavaScript. This means that app developers can use React.JS for building mobile app components. Both React.JS and React Native have base abstractions of React DOM.

Comparing React.JS and React Native


  • React.JS is a JavaScript Library; React Native is a Framework for Building Mobile Apps

React.JS is a JavaScript library that app developers use for designing attractive UI and creating high-performing web apps and UIs.React Native is a mobile app development framework that uses React.JS to let developers create mobile apps with rich UI components and has functions like Hot Reloading that aid in faster development.

  • Both React.JS and Reach Native are Great Tools for Developers

React.JS has a completely managed rendering cycle for its components which helps improve developer efficiency. Developers can better use basic abstractions because React.JS has a simple way of distributing, creating, and using reusable parts. It’s thus ideal for features like clickable buttons, dropdowns, etc. React Native is also a great tool for app developers because it provides reusable native components that compile directly to native making it easier to get the same look and feel in an app. A component-based structure allows mobile app developers to build apps faster while maintaining the UI, speed, and functionality of a native mobile app.

  • Virtual DOM vs. Native APIs

React.JS Development uses a virtual Document Object Mode (DOM) to create better UI and implements changes to one component without impacting the rest of the UI. For developers this is easier because then they make any updates much faster and create exciting UI.

React Native accomplishes the same by using native APIs to render UI components that can be reused across mobile platforms. It uses Java APIs for Android components and Objective-C APIs for iOS. Developers can then use JavaScript to compose whatever remains of the code, fine-tuning the mobile for every platform. That’s why mobile apps developed using React Native have maximum components reusability and code share ability.

  • React.JS is Good for SEO; React Native is great for UI

React.JS uses Node to render on the developer’s server without asking for any special effort or coding and is very SEO-friendly. But React Native is primarily a mobile app development framework so it has nothing to do with SEO. In comparison with other mobile application development frameworks, React Native is fully UI-centered, making it more like a JavaScript library rather than a framework.

  • React.js Combines Technologies While React Native is Combined With Existing Apps

React uses HTML and JS following the rule that they work alongside every time. It also incorporates CSS in order to avoid any problems linked to CSS development. React Native, however, allows mobile app developers to layer additional features on an existing app without requiring a change in the code of the entire app itself. Mobile app developers can choose to add React Native components into the existing code of their mobile app.

  • Set-up and Running

When launching a new project and setting up React.JS, the web app developer will have to choose Webpack which is actually a bundler, and then he will have to pick the bundling modules best suited to the particular needs of that project. But for React Native projects, mobile app developers already have all they require to set-up and get started, making it easy to launch the framework by running just a single command line in the terminal.

  • Animations

React JS uses CSS to introduce animations into web apps, whereas React Native uses JavaScript to create animations for mobile app components. Mobile app developers can use the Animated API to animate whole components, or they can use the very popular JavaScript library called Velocity.JS which allows app developers to build assorted animations based on time and speed of gesture. Unlike React.JS which has limited scope for animations, React Native gives developers the flexibility to do a whole lot more.

Final Word

Using React Native for mobile app development is an obvious choice because it allows mobile app developers to create an attractive and high-performing app in a short time and have it market ready ahead of competition. Even though React.JS is meant for handling UI components, it is easier and faster to create complex UI design elements using React Native as compared to React.JS whether it is for IOS or Android.
