3 Compelling Reasons to Choose React Native for Your Next Mobile App

3 Compelling reasons to choose React Native

Every time a business needs a mobile app built, there’s a dilemma: to choose a native app, a web mobile app, or a hybrid mobile app based on HTML, CSS, and JavaScript. Basically, it all boils down to the money vs performance and appearance battle.

It’s true that native apps look great and work fast on devices powered by respective operating systems. However, they require a larger budget and more manpower, since most companies want to cover the customers who own both iOS and Android-operated gadgets.

By contrast, web mobile and hybrid apps cost less to build and work everywhere. However, they’re limited in their access to a device’s hardware capabilities (camera, sound, etc.) and often have a look and feel that leaves much to be desired. So, can we achieve the right balance between performance and budget at all? Yes, we can. How? We can use React Native, an efficient mobile app framework.


React Native (RN) is an open-source JavaScript (JS) framework that was introduced by Facebook in 2015. Its main purpose is building mobile applications that work and appear as native both on Android and iOS devices.


What's React Native

Let’s break down the framework’s name. The first word of the two denotes a JS library that Facebook incorporated into its ecosystem in 2012. React’s mission is creating highly interactive web user interface elements. More on React here.

The “native” part of the title, as you’ve guessed, means that the framework’s main function is to help build mobile applications using the native UI components of the target operating systems.

What’s Inside RN Apps?

RN apps contain no HTML or CSS code. Only JS. An RN developer just takes the principal user interface components that iOS and Android programmers use and glues them together via JS. As a result, you won’t be able to tell the difference between an RN app and one based on Android or iOS.


Since its launch back in 2015, RN has been steadily gaining a following among the developers’ community. While in 2015 it had more than 30,000 stars on GitHub, in September 2019 it boasted over 80,000.

Many large, respectable companies have opted for building their mobile solutions with RN:

  • Facebook (naturally)
  • Instagram
  • Tesla
  • Skype
  • Wix

What is so appealing in RN that makes it so popular? Here are the main reasons why we recommend this framework for your next mobile project.


Reason #1: One Codebase Instead of Two

React Native: one codebase instead of two

No more need to search for two separate developers or development teams to build your app. All you need is one computer professional who knows JavaScript inside and out, plus is well-versed in Android and Apple user interface blocks and design patterns. This can be very cost-effective for your business.

Once the developer writes the code, any device on Android or iOS can run it. Whenever changes to the app need to be made, only one codebase has to be modified. That reduces the development and maintenance time dramatically. According to some estimates, over 90% of the code for one operating system can be reused on the other.

Reason #2: High Development Speed

React Natvie: High development speed

Another valuable advantage for any business. The sooner you get your app finished, the less money you’ll have to pay, unless, of course, you’ve agreed on a flat rate. RN development is fast thanks to several important RN features.

Simple and powerful syntax

RN uses simple yet powerful JSX (extension to Javascript) syntax based on ES6. JSX is an inline markup very similar to HTML that gets converted into JS. It provides a robust system of classes in Java-like fashion. As such, RN developers don’t have to work with the prototype-based inheritance JS system. At the same time, all statements and expressions are almost identical to JS, meaning every JS professional will find JSX a piece of cake.

Great code reusability

Code reusability speeds up the development process tremendously. In RN, a program is divided into standalone, independent modules that can be reused in another application.

That’s a treat for developers. They can quickly get a grip on any RN project and make any necessary changes to it. That also makes QA specialists happier, as they need less time to learn how the program works and come up with appropriate tests. All this considerably reduces the development cycle of an RN app.

Fast refresh feature

This option, also called “hot reloading” or “live reloading,” lets a developer see the modifications to the source code without having to recompile it. Just place two monitors on your desk. Modify the program in one, and the results will immediately show up in the other.

Extensive support for external plugins

Even the most advanced and time-tested framework may lack some important functionality at its core. RN is no exception. It’s still relatively young — only four years of age at the moment of writing this post. To help developers quickly add a function that the RN core misses, the framework provides support for third-party modules. Example: Modal box

Reason #3: Excellent Performance

React Native is as performant as native apps

Believe it or not, RN apps can be almost as performant as their native counterparts, even though the latter have all the access to a device’s inherent functions. Read this post. Its author created two identical apps by using Swift and RN and discovered that they barely differed in their speed and efficiency.

How is that possible? The thing is that RN architecture is focused on mobile devices and mainly uses the Graphics Processing Unit resources, while native apps mostly consume the Central Processing Unit resources.


React Native seems to have resolved the years-long mobile app development dilemma “performance and appearance against budget.” This framework allows developers to create visually appealing programs with excellent performance characteristics at a relatively low cost and do so simultaneously for iOS and Android.

That’s why PSD2HTML developers highly recommend you RN for your next mobile project.
