In today’s scenario developers used React Native framework for the development of native apps with iOS, Android, PhoneGap, Hybrid apps, and Xamarine. The Architecture of React Native comprises four layers namely application, 3rd party libraries, Developer SDK’s and Mobile OS. The most special feature about React Native is; it allows you to write one code which suits both platforms iOS and Android. In this blog post, various features and limitations of the React Native framework would be discussed which will help you to qualify to React Native Interview Questions.

Given below are the features of React Native


It is one of the best features of React Native which implies that a code which is written in React Native can be used in almost every mobile platform such as iOS, Android, Windows, etc. You can use the code which is designed to React Native formwork as it evicts the need of writing code in java for Android, C# for windows and Swift for iOS.


When it comes to cross-platform application development React Native framework is a trusted framework. In all mobile applications, Facebook uses React Native due to its trustworthy features. In addition to this, React Native is used by a number of companies namely Tesla, Walmart, Discord, Skype, Instagram Airbnb, etc.

Npm for installation

React native uses NPM for the installation and it is fairly easy to use it as compared to other programming frameworks. People with Non-JavaScript are having vast experience with NPM. Even, it is not difficult for people to learn NPM commands.

Mobile Environment performance

The applications which are developed using React Native are GPU oriented while most of the native applications are CPU oriented. It is a well-known fact that GPU oriented applications are posing better performance and speed as compared to CPU oriented applications.

Live Reload

Live reload is one of the special features in React Native as it provides two screens, one to view the modifications and one to modify the code. A mobile application developer who has experience in mobile development using React Native knows how this feature will make a difference.

Given below are the limitation of react-native

  • The architecture of React Native is not optimal in comparison to Flitters. The architecture of React Native is based on Flux architecture that uses a bridge to establish connectivities with the native modules. The bridge uses for the establishing of the communication channel between the Native modules are termed are JavaScript bridge.
  • It supports limited testing options which imply that the React Native framework support unit testing but it does not support integration or UI level testing because no official tools are used for it.
  • It is easy to learn React Native for people who are belonging to a web background. However, for fresher react Native is a quite complicated and complex language.


As you can see, React Native is more than just a suitable platform for the development of a scalable application and marketplace platform, which can work in an on-demand model. With the help of this blog, you will get a clear view as all the Best Interview Questions which are related to React Native are quoted in the blog. With the help of React- Native framework, you can provide more than the standard, default app functionality.
