2021-07-16 by walter smith

React Native is a JavaScript library that allows app developers to create an application that looks, feels, and performs closely like a Native application. It works on the same fundamental UI structure as usual Android and iOS apps. All you need to do is just put the structure together with the help of JavaScript and React. And The most interesting part is that it works similarly to the concept for building cross-platform apps. 

The fundamental of React Native is to induce React to mobile apps. and it is based on studying once and implementing anywhere. And one great option that outshined for cross-platform app development is React Native.

Why React Native apps over Hybrid/Native apps?

There is no doubt that Native apps deliver the best performance. But, it is expensive because it requires two apps - iOS & Android. The use of a single codebase makes it faster and cheaper.

    How does React Native work?

    To understand the functioning of React Native, we'll divide it into three sections-  javascript, native, and the bridge.

    The main thread on the native side is called the UI thread. The thread is employed to perform the UI in Android or iOS. It deals with showcasing details of the user interface and other UI events such as touch, press, etc.

    On the Javascript side, there is a Javascript thread that is particular for React Native. From here javascript codes are implemented. And API calls are performed, etc. It specifies the layout and highlights of the UI.

    These two threads communicate through a bridge. And this is the heart of React Native structure. The bridge helps in two-way communication between Javascript and native. Also, transfer communications in an optimized manner.

    Who is using React Native?

    Nothing beats practical cases. These famous apps have been built on React Native:

    • Facebook And Facebook Ads

    As mentioned above also, React Native was a part of Facebook’s project. It was originally developed for iOS app development. But later prolonged for Android as well. Facebook Ads used React Native for android for the first time. It resulted in lightning-speed smooth animations. To check the effectiveness of React Native, the tech team transformed the Events Dashboard on Fb for the iOS app. It showed outstanding performance enhancement, and with this, it became twice as fast as the previous one.

    • Instagram

    Instagram also took a big step when they took the decision to move their app to newer technology. They started with small but later moved the whole app to the platform.

    • Walmart

    Walmart also revised its app to enhance the customer experience. React native helped their app perform fast and smoothly.
