What Is React Native:

React Native: It is a framework developed by Facebook for creating native-style apps for iOS & Android under one common language, JavaScript. ... However, with its recent support of the Android operating system, the library can now render mobile UIs for both platforms. Prerequisite: Basic Knowledge of HTML, CSS and JS.

If you need to develop an app for both iOS and Android, React Native is the best tool out there. It can reduce the code base by about 95%, saving you time and money. On top of that, React Native has a number of open-source libraries of pre-built components which can help you further speed up the development process.

The fact that React Native actually renders using its host platform’s standard rendering APIs enables it to stand out from most existing methods of cross-platform application development, like Cordova or Ionic. Existing methods of writing mobile applications using combinations of JavaScript, HTML, and CSS typically render using web views. While this approach can work, it also comes with drawbacks, especially around performance. Additionally, they do not usually have access to the host platform’s set of native UI elements. When these frameworks do try to mimic native UI elements, the results usually “feel” just a little off; reverse-engineering all the fine details of things like animations takes an enormous amount of effort, and they can quickly become out of date.

The first and foremost reason to use React Native Framework is that the developer has to write one set of code, i.e. JavaScript code, to enjoy the performance of the REACT Native Mobile Applications. Let’s take a sneak peek into some of the pros and cons of using REACT Native Framework here:

For developers accustomed to working on the Web with React, this means you can write mobile apps with the performance and look and feel of a native application, while using familiar tools. React Native also represents an improvement over normal mobile development in two other areas: the developer experience and cross-platform development potential.
