React Native is a JavaScript framework for building real-time, natively rendered iOS and Android mobile apps. It’s based on React, Facebook’s JavaScript framework for developing user interfaces, however, it’s geared more toward mobile than online platforms. In other words, web developers may now use the familiar JavaScript framework to construct mobile applications that look and feel completely “native.” React Native also makes it simple to develop for both Android and iOS at the same time because most of the code you write can be reused between platforms.

React Native is now available for iOS and Android, with the possibility of future expansion to more platforms. This book will go through both iOS and Android. The vast majority of it will be written as cross-platform code. Yes, you can utilize React Native to build production-ready mobile apps. A few anecdotes: It’s already being used in production for user-facing applications like Facebook, Palantir, and TaskRabbit.

Advantages of React Native:

By rendering using the host platform’s normal rendering APIs, React Native distinguishes itself from most other cross-platform application development methods, such as Cordovan or Ionic. Web-views are often used to show existing techniques of developing mobile applications utilizing a combination of JavaScript, HTML, and CSS. While this technique has the potential to be effective, it also has drawbacks, especially in terms of performance. Furthermore, they normally do not have access to the host platform’s native UI elements. When these frameworks attempt to emulate native UI features, the results frequently “feel” a little odd; reverse-engineering all of the minute details of things like animations take a lot of time and effort, and the results can quickly become outdated.
