What is React Native?

React Native is an open-source JavaScript framework developed by Facebook. It is used for developing a real, native mobile application for both Android and iOS platforms. It is a JavaScript framework that builds upon the React library to create mobile apps with a single codebase. It uses native components rather than using web components as building blocks. It has a cross-platform feature, which allows you to write code once and can run on any platform. It saves your development time as it will enable you to build apps by using a single language JavaScript for both Android and iOS platforms.

Features of React Native

React Native provides many advantages for building mobile applications. Some of the essential features of React Native are given below:

Open-Source: React Native is free and open-source. It means anyone can use it easily.

Cross-Platform: It offers the facility to “Write once and run everywhere.” It is used to create apps for Android, iOS, and Windows platforms.

UI Focussed: React Native is mainly focused on UI. It makes the app interface highly responsive.

Performance: The code written in React Native is compiled into native code, which enables it for all operating systems to provide closer native appearance and functions in the same way on all platforms.

Hot Reloading: Making a few changes in your app’s code immediately visible during development. If the business logic is changed, its reflection is live reloaded on screen.

Support For Third-Party Libraries: React Native support many third-party libraries to make an app interactive.

Faster Development: React Native allows you to reuse the code which is already written. This feature helps you to develop apps fast. It uses a common language to build an app for Android, iOS, and Windows platforms, which gives speedier app deployment, delivery, and quicker time-to-market.
