Why Build Mobile Apps in React Native?

React Native is the hip new framework that was open sourced by Facebook in early 2015. Since its release, there has been a very steady growth of interest in the framework. Not to mention it has amassed over 47k stars on GitHub. It empowers developers to create apps in Javascript that run on multiple mobile platforms like iOS, Android, Windows Universal Platform, and others.


With reactive-native, you can now build a real mobile app that’s indistinguishable from an app built using Objective-C or Java. It uses the same fundamental UI building blocks as regular iOS and Android apps. You just have to put those building blocks together using JavaScript and React.


So let’s take a look at why this is so cool


Lightning fast feedback loop

React Native gives you freedom and speed. The compile times are nearly gone. By adding file watchers you can automatically reload the app when you save a file. There are instant updating and viewing. Making and experiencing the changes in real time gives you incredible focus. You never have to wait to see your changes get applied to the app. They are always instant. Imagine the great amount of wait time cut short for a developer.


Boon of Cross Platform

React is a great abstraction that can be adapted to multiple platforms. The time and cost efficiency are covered by the fact that by supporting a single codebase it is easier to understand. Apps like Facebook’s Ad Manager app uses the same, and they have 85% code sharing between multiple platforms (iOS and Android). Any small or huge business can cut their costs by half with react native.


React Native is a beauty!

The principles are very similar to React here. React Native maintains a virtual representation of the view hierarchy. When changes are made, the virtual hierarchy is compared using an efficient diffing algorithm. This saves the overhead of performing complex operations on the view hierarchy. Once the comparison is done with the clone, appropriate changes are made to the actual view hierarchy. The most dreaded; managing state operation of UI is hence evaded.



Simplicity is the key to development. While most developers use Xcode and Android Studio the fact is undeniable that they can be slow and hard to use. What we have here is a plain text editor which doesn’t crash, it doesn’t hang and it doesn’t lose syntax highlighting randomly! The result? An increased overall productivity.


Enough with the talking now! The awesomeness needs to be experienced first hand. What’s better than a Learnup camp where you’ve to build stuff yourself and wait-o-wait you can take away truckloads of hands-on knowledge and maybe a cool job offer home?
