The ReactJS vs. React Native Dilemma: How to
Make the Right Choice
React Native and React (also known as ReactJS), apart from owing their existence to
Facebook have one more thing in common – JavaScript. Both pride themselves as the
progressive technology that drives mobile and web respectively.
React JS is a JavaScript Library that helps simplify the development process, build
high-performing web apps and help deliver impeccable UIs. React Native on the other
hand is a popular mobile app development framework used by mobile app developers
to build Android and cross-platform applications.

Also referred to as an extension of React JS, the main focus of the React Native
framework is user interface, visual effects, and its immaculateness. React Native have in
the past few years emerged as the most sought-after mobile application
development framework by 1000s of businesses worldwide from Facebook,
Instagram, Bloomberg, Skype, Soundcloud Pulse, Pinterest, and AirBnB to name a few.

Let's Talk - Efficiency
‘Both’ React Native or React JS Enhances Developer Efficiency
Looking to build beautiful user interfaces for your business? ReactJS is the JavaScript
library that does that for you. One of the unique features of ReactJS is that they can
function together interoperable, i.e. it can perform on the client-side, while being
rendered on the server-side. So, what do you get out of it?
ReactJS not only helps you enhance developer efficiency, but also empowers them with
added opportunity to utilize while making basic abstractions. Simply speaking, it is
equally valuable for lower level parts like clickable buttons and higher-level parts
like dropdowns.

However, for React Native, a different approach is adopted to maximize developer
efficiency. Components you would use in Android or iOS have counterparts right in
ReactJS, so you will get the same look and feel. Reusable native components compile
directly to native that form the building blocks in React Native. Here the app will have
the look, speed, and functionality of a native mobile app that makes React Native unique
and STAND OUT from other mobile app development frameworks.
Moreover, the React Native framework also allows highly experienced engineers to add
native codes (Java, Swift, Objective-C etc.) to the framework, so as to help achieve that
custom look.
The success and the future of React Native is very much secured with these simple
words of realization from the Facebook founder – clearly giving direction to the many
advantages of building mobile apps using React Native framework.
Let's Talk - Feasibility
Combine Technologies with React JS
React or ReactJS combines technologies, where HTML and JavaScript, comes together
continually. Now, it is also concluded that this is done mainly to include CSS, which
rejects a bunch of issues identified with CSS development, such as worldwide
namespace, and variable/scope isolation.
Add Code with Any Existing App in React Native
Are you looking to add more to your existing app, but not preferring to change the code
of the whole app? React Native can help make it possible for your business. You can just
add React Native components into your existing app’s code. And in case your current
hybrid app was built with Ionic and Cordova, you can reuse that Cordova-based code
effectively with just a plugin.

Let's Talk - Capability and Prowess
Boost SEO for Web App with React JS
React JS is was designed keeping Search Engine Optimization (SEO) in mind, wherein it
uses Node to render on the server of the user. Although there are similar tools to give
this server viewpoint to rendering, they usually call for a ton of unstable hacks. This is
apart from an extensive amount of developer support that is required for maintenance.

Build Responsive UI with React Native
React Native on the other hand, is exclusively dedicated to building a mobile UI. This
means, besides being completely UI-centred React Native makes for more like a
JavaScript library rather than a framework. Hereby, the resultant UI is remarkably
responsive that delivers a much smoother feel to the apps along with speedier load
times.

Let's Talk - How it Works
What works behind the scene for both of these amazing technologies – ReactJS and
React Native is what everyone wants to know. While React Native makes use of native
APIs to render UI parts that can be reused over and again on both iOS and Android
platforms, ReactJS harnesses the power of the virtual DOM (Document Object Model) to
create better UX.
Virtual DOM for ReactJS
DOM as you know, is about the logical structure of documents and the way it is accessed
and manipulated. However, it takes time to build one and DOM trees nowadays are
large. But, when you use React JS, it manages to accomplish this procedure faster and

seamlessly by utilizing a virtual DOM that helps in making quick updates, while creating
dynamic UIs. ReactJS does it by simply making use of an abstract copy of the Document
Object Model, making the required changes to the ‘one component’ and that too sans
influencing the rest of the UI.
Native APIs for React Native
On the other hand, React Native uses Objective-C APIs to write iOS components and
Java APIs to render Android components. Thereafter, JavaScript is utilized to compose
whatever remains of the code and customizing the app for every platform – ensuring
maximum reusability of the components and shareability of codes.
While ReactJS uses HTML and CSS, React Native does not. You will have to create style-
sheets in JavaScript so as to style your ReactNative components, which even though may
look similar to CSS, but are not closely the same. Similarly, ReactJS uses <p> against
<text> in React Native, while <div> in React is used instead of<view>for React Native.
Here is an example to show the same:
For ReactJS

For ReactNative
Protip: To run your app built with React Native, you will need to have Android Studio
(for Android) or Xcode (for iOS, on Mac only) installed on your computer. Thereafter, you
can either decide to run it on a simulator/emulator of the platform of your choice or
directly on your own devices.
Over to you…
It is great fun using both ReactJS and ReactNative tool. Developers who are adept at
ReactJS have an edge, as they can also build great applications in React Native. React
Native is damn fast and takes 33% less time than building an Android or iOS app
natively. In fact, it allows you to build complex UI as quick as you would do with ReactJS
that works quite well for both iOS and Android. Another great thing about working with
ReactNative is that it allows the use of most developer tools (such as Chrome Dev Tools,
Redux DevTools, etc) used with ReactJS.
