Introduction

In this blog, you will get introduced to the fundamental concepts of React Native and explore the various features present in React Native. It is good to have a basic understanding of Javascript fundamentals to quickly understand the features of React Native, although this is not a compulsion. 

React Native

React Native is used to designing and create mobile applications that work on Android and IOS operating systems. React Native is a Javascript framework; therefore, it uses Javascript to build mobile applications which run on mobile devices and not on browsers. React Native apps are not Hybrid apps, and everything is compiled into native code before running. This framework of React Native was developed in 2013 by a very well known company called Facebook (now known as Meta). It is an open-source framework, i.e. its code is publicly available on Github.

Setting up React Native Environment

You need to install a few things on your machine before you start making beautiful cross-platform applications using React Native. The installation process is a simple 3 step process. The first step is to install NodeJS and NPM Package Manager. The next step is to install a favourite editor/IDE to write code. The last step is installing and setting up the Command Line Interface to run and debug your applications.


Refer to the blog React Native Development Environment Setup on the Coding Ninjas Website to see a more detailed description of these steps.

Advantages of React Native

There are a lot of advantages of using React Native as your application development framework. We will discuss briefly a few of them in this section.

Performance

React Native is a Javascript framework; thus, it guarantees good performance. Also, the same codebase can be used for both Android and iOS, increasing performance. 

Hot Reload

This is a helpful feature for the developers. If you make a small change to your codebase, the change will be directly reflected on the output device/emulator without re-running the app.

Support for Cross-Platform

The applications developed using React Native work on both Android and iOS devices. This is primarily because the code written in React Native is compiled into native code.

Limitations of React Native

Although React Native is a trendy and widely used framework these days, few limitations are associated with this framework. For example, a person will have to write a platform-specific code if they want to create a native functionality which does not exist yet. Another fact is that the ownership of this Framework lies with Facebook, which may withdraw this framework at any point in time in the future, although the chances of occurrence of this event are rare.
