React Native is a JavaScript framework specifically designed for building truly native apps for both iOS and Android platforms. Created by Facebook, this framework is based on the popular React library and brings its power to mobile app development. In today’s mobile app development market, businesses often face a tough decision:
· Build apps that provide a superior user experience, or
· Build apps that are faster to develop and run seamlessly across multiple platforms and devices.
React Native offers a solution to this dilemma by allowing developers to create apps using a single paradigm for all platforms. With React Native, the app development process is streamlined as most of the code can be reused across different platforms. The result is excellent performance, nearly identical to that of native apps, with smooth animations.
React Native is essentially a native version of the popular React web library, designed to empower mobile app development. The components in React Native are pure, side-effect-free functions, returning what the views should look like at any given time, which contributes to an excellent user experience.
One of React Native's key advantages is its ability to allow developers to write native apps in JavaScript for both Android and iOS. This includes access to native components like gestures, push notifications, the camera, and location services. React Native’s rendering uses actual native views, so the user experience is far superior to other solutions that rely on a web component within a WebView.
React Native started as a hackathon project at Facebook to address their specific needs. Facebook wanted to bring the advantages of web development, such as rapid iterations and having a single development team, to mobile platforms. This is how React Native was born, eventually becoming a key tool for mobile app development for both iOS and Android.
Why Did Facebook Choose React Native?
Initially, Facebook developed React Native to support only iOS, but with its recent expansion to Android, the library now supports mobile UIs for both platforms. Facebook used React Native to develop their Ads Manager app, creating both iOS and Android versions with the same development team.
