What is React Native?

React Native is an open-source framework for more desirable mobile application development with extensions to web application development as well. It was published by Facebook in March 2015. React Native is one of the most popular and commonly used cross-platform mobile application development frameworks nowadays. It is used from Android to the development of iOS applications, to Web applications, and even for UWP (Universal Windows Platform). 

React Native is a fusion of ReactJS with Native platform capabilities. React Native is influenced by React, so the fundamental notion of the information course is similar to React. It is easy to call and execute  Native language functions from React Native (Native modules). Native modules are developed in Objective-C classes that can be available through  JavaScript as well. One occurrence of each segment is built as per JavaScript Bridge. They transport arbitrary functions and constants to React Native. The design outlook of a React Native App Development segment is being derived from Native. One of the most extraordinary things about React Native is that it’s “actually” Native. Other JavaScript-for-mobile frameworks encase your JavaScript code in an acclaimed web view. They might re-carry some Native UI code and performance, like the animations, but you still are writing a web app.

Why React Native?

React Native is one of the first cross-platform frameworks with lots of Native components and React.js features to be ever-developed. There are various reasons to choose React Native for App development.

Both iOS and Android secured

The primary agenda of Facebook to build React Native is to support iOS only. But in the following years, Android grew more popular and started to be used not just as an operating system in mobile devices but in TVs so React Native added Android libraries and APIs as well. So to meet the market need, since then React Native is being utilized for both types of mobile operating system applications that are Android and iOS. That too with “code once, execute anywhere approach”. 

Multifaceted Javascript System 

React Native is created with Native components, React.js and JavaScript.  React Native is conceivably one of the most adaptable and resourceful JavaScript frameworks. It permits any front-end web designer to be a compact application developer on the spot. React Native app development gives the freedom to mobile app developers not to an expert of different languages like Kotlin for Android or Swift for iOS because comprehending JavaScript, some local UI components, stage APIs, is all to develop your own applications in React Native. 

Native Components

React Native is all about expeditious web application development and mobile applications development. As React Native contains the majority of the features of React.js more vigorous application execution is granted, and it has Native components which help in better designing the templates with lesser complications.  

Faster developing 

React Native allows mobile app developers to make applications faster with various ready-to-use components and tools. React Native is modernizing every now and then, which means most of the required solutions will be available soon.

One Framework for Multiple Platforms

React Native facilitates copying of the code between different platforms. That is the developer needs to write the code once in JavaScript and it can be executed on a different Operating System without being worried about the changes or the programming language barrier.

React Native Mobile App Development vs Native App Development 

React Native for App Development 

Time and Cost-Effective 

While comparing two development techniques the two most important questions are – what will be the React Native App Development Cost and will it be time-efficient in comparison to other types? To put you out of your misery, yes, React Native Mobile App Development is far more cost and time effective in comparison to Native App Development. Because there will be a single UI and UX that can be used for multiple platforms. 

Real-Time Execution 

Hot reloading is real-time monitoring of code even before you get to write the complete application. You can execute a small completed segment of the code in real-time, to check the progress of the application. 

Similar UX and UI Exposure 

React Native developed mobile applications that provide a similar user experience and user interface for both android and iOS users irrespective of the platform. The React Native developed application will have the same features, same UI, same UX, and same outlook. 

Single code 

React Native truly works on the principle of write once, run anywhere. For React Native development for the mobile app, you only need one codebase that can run on any operating system. 

Native App Development 

Better Performance 

Native app development definitely provides better performance because they are built for a particular OS. 

Better UI and UX

UI and UX are much better and of course, provide endless opportunities for updates and changes as per new technologies that won’t be easy for React Native developed applications. 

More Secure

Native mobile applications are more secure because all the security measures are taken into account while developing the application which is confined to a singular platform. 

Top-notch Functionality 

Native apps have top-notch functionality and better access to hardware and other operating system-specified tools.
