Key Difference of React JS and React Native User Guide

React JS and React Native technologies are so influential that many of the popular web and mobile applications in the world are developed with these two technologies. Both are well known for creating web and mobile user interfaces (UI) with the use of JavaScript. However, there are a few similarities and differences in their features and benefits that are described below.

The Key difference between React JS and React Native:

React JS

It is an open-source and front-end Javascript library developed by Facebook for superior UI development and resourceful DOM (document object model) manipulation. React JS or simply React handles view layer for web and mobile apps. It also helps create reusable UI components.

React works on the concept of virtual DOM. When any data is received from the server then virtual DOM has modified accordingly and is matched with real DOM by some algorithm. After matching, only those portions of real DOM are updated which are dissimilar from virtual DOM.

React JS is one of the most admired JavaScript libraries currently having a strong foundation and large community behind it. Make sure you hire an expert React Js developer so that everything works smoothly.

Benefits of React JS:

  • React is mainly useful in creating websites, web apps, and SPAs, etc.
  • This Javascript library is used for developing UI hierarchy.
  • It manages the rendering of UI components and is considered a V part of the MVC framework.
  • As React’s virtual DOM refreshes only required parts of the page, it is faster than the conventional full refresh model. It results in decreasing the page refresh time.
  • Coding time is saved with React because it uses components as the basic unit of UI.
  • React is simple to understand and easy to learn.
  • The best part about React is its partial DOM refresh that leads to increased performance and faster programming.
  • You can reuse code components in React JS, saving you a lot of time.
  • The complete rendering of your pages from the server to the browser managed by React will improve the SEO of your web app.
  • It enhances the debugging speed that is quite a relief for a developer too.
  • Even if you are unfamiliar with React, it is easily readable for you as well. In the case of many other frameworks, you have to learn a broad list of concepts that are useful within the framework only. React attempts to do the opposite of it.
  • It gives you the benefits of all the advancements in the Java language and its network.

React Native

With React Native, you can create real and excellent native mobile applications in JavaScript only, supportable for both Android and iOS platforms devices. Coding for just one time will make the React Native apps available for both iOS and Android platforms. This saves a lot of development time.

React Native also has great popularity as it’s created by Facebook and has huge community support today. It allows you to use React JS, which is an excellent option for AngularJS, to put together your components and implements ReactJS under the hood. It comes with all the advantages that React.js brought to you, for example, a better UI.

Look for the best React developer that guarantees the correct development and proper functioning. 

Benefits of React Native:

  • React Native makes use of native modules and native components that improve performance. React Native renders certain code components with native APIs and not from WebView as used by other cross-platform networks.
  • It allows developers to reuse the common logic layer, so it’s not required to build the same application for iOS and Android separately.
  • With React Native’s component-based structure, developers can develop apps with a more agile, web-style approach to development as compared to most hybrid frameworks, and that too without any web at all.
  • For those who know JavaScript, React Native will be very easy to pick up, and hence most front-end web developers can also easily become mobile developers. Make sure you are well versed with JavaScript, some native UI elements, platform APIs, and platform-specific design patterns if required and you are all set.
  • If you just add React Native UI components into your existing app’s code, you don’t have to rewrite it or overhaul your old app.
  • React Native brings about responsiveness, high speed, and agility of web app development as well as powerful processing and best user experience to the hybrid space that all gives your users a native app experience.


Though React JS and React Native contain similar names with the same parents, as well as a common technology backbone, there are differences between the two. React.js is a JavaScript library that is mainly used for constructing a high-performing UI layer whereas React Native is an entire platform with which it gets easy to build native and cross-platform mobile apps. Hire React Native Developer for utmost advance mobile app development which benefits your business and helps generate new customers.

In simpler words, it can be said that React is perfect for building dynamic, high-performing, and responsive UI for your web interfaces, while React Native is more helpful in giving your mobile apps a truly native feel.
