Mobile App Development: An Overview of React.js & React Native

A Comprehensive Guide to React.js and React Native

Post By :   AppTech Corp.

In the realm of mobile app development, developers are putting all their efforts to shorten product development cycle, improve deployment speed, and enhance performance. To achieve the highest optimum results, React.js and React Native have become the two most trendy and groundbreaking tools.

React.js is the heart of React native. Both of these technologies are being used by leading companies such as Apple, Netflix, and PayPal to develop web & mobile applications and user interfaces. So, without further ado, let’s learn the ABC of both these platforms:


React.js, or often referred to as React, is a flexible, declarative, and efficient JavaScript library responsible for building a hierarchy of user interface components. Simply put, it is accountable for the rendering of multiple UI components. It supports both front-end and server-side scripting to design web and mobile applications and complex UIs.

Remember, React is just the V part of the Model-View-Controller (MVC) framework, a software class meant to receive and package data from the controller of the MVC and display it to the users. Here are the top five benefits of using React.js for your projects:

Virtual DOM object, a lightweight copy

Virtual DOM (document object model) is a logical structure of several documents in XHTML, HTML, and XML formats. To describe it in layman’s language, it’s a schematic arrangement of data (inputs and outputs), which forms a tree structure.

Unlike other latest frameworks that use real DOM, React.js works with its abstract copy, a virtual DOM. Instead of the conventional full refresh data model, it uses one-way data binding to make the whole process faster and simpler, enabling the virtual DOM to refresh only some parts of the webpage as opposed to the entire browser. Virtual DOM updates even the minimalistic changes, makes the user experience better, increases performance, and enables developers to work with complex UI-objects faster.

Reusable composed components

React.js empowers developers to reuse the same composable and stateful code components on mobile and across the web, thereby saving their time significantly. The declarative components let them create great and interactive mobile user interfaces. If designers could not reuse the assets, they’d have to create corporate logos, for instance, over and over again.

When composing interfaces, you can categorize the common design elements, including buttons, layout components, form fields, etc., into reusable components with well-defined interfaces. This makes it easier because when you build your next interactive UI, you can use the same components and can modify them as you see fit. This leads to faster development time, fewer bytes, and lesser bugs down the wire.

Reach innovative developer tools

Learning new technological advancements and using them for your next big project can be terrifying yet challenging. React offers latest and innovative debugging and designing tools, which makes a developer’s life easier. These tools empower programmers to observe reactive component hierarchies, discover both parent and child components, and inspect their current state.

Easy-to-learn – even for beginners

Any JavaScript developer can easily mug up React.js as the learning curve is not as steep as compared to other frontend frameworks such as Angular. Even those unfamiliar with React.js can apprehend its basic concepts. Many frameworks are complex, and thus require developers to study an array of concepts and models which can be used within that specific framework only; however, React strives to do completely opposite. The developers can start building excellent web and mobile apps after mastering the basics, tutorials, and docs within a few days.

JSX extension

JSX is a JavaScript syntax extension that provides support for pseudo-elements in the JS applications. Generally, its XML syntax provides a big help in creating new DOM nodes in JS. It makes it easy to understand how the components are conjoined with each other. Additionally, it allows React.js to flash errors, warnings, and other useful messages.

React Native (RN)

React native is an open-source framework emerged from Facebook that enables developers to build native applications for both iOS and Android platforms using a single react codebase. The best thing about this framework is that you don’t need to create several different applications such as a mobile, web, HTML5, or a hybrid app.

RN empowers you to reuse the same source code and deploy it on mobile and across the web, thereby helping you develop a real-time mobile app every time. The real-time application is actually indistinguishable from any app created using Objective-C or Java. Additionally, with the data-driven approach, you can even include various graphical elements to match the consistency of a platform. In the nutshell, RN has brought the concept of web app development into mobile app development using the JavaScript library and React.js together. Let’s take a look at the benefits of using React Native framework:

Supports both iOS & Android platform

With the traditional development approach, developers have to design a single app twice in order to make it compatible with both iOS and Android. By using RN framework, however, they can work with the single mobile UI while developing the app for both Android and iOS platform at the same time.

Native modules & controls

React Native comes with Native controls and Native Modules, which help developers renovate the old applications and improve efficiency. All they need to do is include native UI elements and implement libraries with APIs into the code of an existing app, without rewriting the whole code. React Native comes with all the advantages that React.js made you familiar with.

Save time and improve efficiency

It combines the power of JavaScript and React.js. If you want to save 40 percent of development cost and time without sacrificing the performance of an application, then React Native is your best bet. In terms of debugging and learning, JavaScript is much simpler programing language. React Native’s component-based structure allows developers to build native and hybrid apps, such as UIWebView in iOS and WebView in Android, with a more subtle, world-wide-web style approach.
