React JS vs. React Native: Everything that You Wanted to Know
With the challenge to develop a top-notch, highly dynamic and user-
friendly app that reacts and renders data as per user requirements in 
minimal time, the social media giant – Facebook – came up with React.
And that’s how the name for the globally popular library came up. This 
library was brought into the picture in 2011 with its development roots 
in JavaScript and XHP symbiosis. Due to this radical implementation 
that offers high performance and incredible responsiveness to the user, 
it is being taken up as a framework in suitable scenarios.
However, Facebook dealt with a two face challenge – to create 
interactive UI interfaces for the web app and 
mobile app development as well. And it is correct to say that it 
achieved both of the goals. So, read on to find out all about React and 
its subordinates.
First Things First
Before we dive into the what, why, and how of React, we need to establish a common 
and clear understanding. The most important one being – React is an open-source 
library. It can be used for developing web-based as well as mobile-based applications. 
And for meeting the requirements of these two platforms, React has evolved and 
further segregated.
React JS is the library primarily known for developing single-page websites, whereas 
the React Native framework is implemented to create mobile-based applications. 
They both are based on React and serve different purposes.
Understanding React JS
As mentioned earlier, React JS is based on JavaScript, but JavaScript lacks the power 
to render dynamic and highly responsive web pages. Hence, a revolutionary 
development approach was taken up.
Along with JavaScript, the developers used XHP symbiosis to develop a library that 
renders data and desired pages in no time. It is extremely reliable in creating UI of 
web-based applications.
Apart from that, React JS uses the ideology of creating an application skeleton 
through reusable components. This approach assists the developers in creating a 
faster and robust application.
Advantages and Examples of React JS
Some of the commonly known reasons which make React JS a preferred choice 
for developing web applications are:
•Easy to Learn: Since React JS is based on JavaScript, it is easy for any 
developer familiar with the latter to learn and create web pages in the former.
•Dynamic Web Pages: Before React JS was introduced, it was tricky to develop 
dynamic web pages using simple HTML. And that is the biggest hurdle React JS 
has come over. These pages can be developed with simple code, and in less time 
as React, JS handles the complexity.
•Implements Reusable Components: The logic behind reusable components 
is that the developers can now write separate web pages, and while they may, 
some use common features. This reusable code helps in easier development as 
well as maintenance. Some of the applications developed using React JS are 
Apple Music, Spotify, and Facebook web app.
Understanding React Native
React Native is the framework that is favoured for developing mobile-based 
applications. To be more specific, it is a hybrid development framework that uses 
native application development and JavaScript UI development.
This framework allows up to 95% of the code reusability, where computationally 
complex implementations are made using native mobile development modules. 
The native look and feel can be easily developed with React libraries, which are 
advanced enough to build a cross-platform mobile app.
Advantages and Examples of React Native
•Leverage of JavaScript Programming Language: Indeed, JavaScript is one 
the fastest and developer-preferred languages globally, with more than 60% of 
developers using it to date. The benefits of this language were earlier limited to 
web apps only, but with React Native, they are now accessible and implemented 
for mobile-based applications.
•Improved App Performance: Code components of React Native directly 
connect with desired iOS and Android components in a different thread, 
enhancing the app’s performance.
Supports Debugging: In the latest release, React Native now allows its users to 
debug the code and fix the issue before any planned release. It includes the 
capability to view crash reports, network request performance, and interact with 
the device database. Some of the applications developed using React Native are 
the Facebook mobile app, Walmart, Airbnb, Instagram, and Tesla.
React JS vs. React Native
It is evident from the information you have gone through so far that React JS is a 
popular choice among developers for creating interactive and highly responsive 
web pages. While on the other hand, React Native is a favourable option that 
allows code reusability and enhanced UI of the mobile-based applications.
Let’s have a look at a couple of comparable features and understand how 
ReactJS and react-native differ:
DOM (Domain Object Model): This element plays a colossal role in displaying 
the application’s elements at runtime. So, React JS uses its Virtual DOM for better 
performance, where the need to refresh pages after every change is removed. 
This is one of the primary reasons for better application rebuilding and 
performance.
Navigation: React JS is primarily powered by the React library and which in turn 
is implemented using JavaScript. The flow is relatively simpler and quite ideal to 
create dynamic web pages to meet today’s user end requirements.
React Native is all about the native devices for each mobile handset. With the 
focus to deliver a better phone performance, the preliminary JavaScript is 
deployed on the devices using native support code. The deployment of native 
screens also enriches this.
