React Native combines smoothly with components written in Objective-C, Java, or Swift. It’s simple to drop down to native code if few aspects of the application need to be optimized. It’s also easy to build part of the app in React Native, and part of the app using native code directly – that’s how the Facebook app works.
Thousands of apps are using React Native, from established Fortune 500 companies to hot new startups. Some of them are:
Facebook – iOS and Android
Instagram – iOS and Android
Airbnb – iOS and Android
Skype – iOS and Android
Tesla – iOS and Android
Bloomberg- iOS and Android
Gyroscope – iOS
Tencent QQ – Android
Townske – iOS
Artsy – iOS
Walmart – iOS and Android
Advantages of React Native
Maximum code reuse & cost saving
By using React Native, you can use the same code for deployment on iOS as well as on Android. This means a huge saving in development time and cost. Theoretically, the development effort could be cut by half.According to recent calculations, about 90% of the code can be reused between Android and iOS.
React Native might be considered as the mobile next step after React: It builds on the React ideas and allows us to create powerful mobile applications. It has an interesting feature that will not be found in the native frameworks: the ‘live reload’ feature, which enables to immediately see the result of the latest change made to the code.
Strong performance for mobile environments
The React Native architecture is very well tuned to mobile devices. It makes use of the GPU-Graphics Processing Unit, while native platforms are more CPU-Central Processing Unit intensive. Compared to hybrid technologies – which was the only option for cross-platform in the past – React Native is superfast.
Modular and intuitive architecture similar to React
The modular and intuitive interface makes it very easy for other developers to delve into someone else’s project and build upon it. This increases the flexibility within a development team, and makes it easier to create updates and upgrades to web applications. Additionally, testers will need less time to understand the programming logic and build appropriate testing scenarios. This will lead to valuable time-savings, especially when this advantage is extended from web to mobile and vice versa.
