react js for web & mobile app

React JS is the buzzword among many developers nowadays. When Facebook was released back in 2011, numerous technologies were already ruling the development market such as Angular and Node. However, these frameworks required coders to rewrite a significant portion of their code when any of the components needed changing or modification. 

Frequently, doing so exploited a considerable amount of developers’ time and energy, which was magically eliminated as soon as React JS entered the market.  They got the framework they had always searched for with ReactJS.simplified their working process that could easily segment complicated components, where the code could be reused for different operating systems. As a result, ReactJS migration is one of the most in-demand services among the coders’ community. 

Today, the flexibility, simplicity, and better performance than ReactJS brings to the table are unparalleled in the software development market. 

What is ReactJS?

ReactJS is a component-based, open-source JavaScript library used extensively to build interactive, intuitive, dynamic, and user-friendly interfaces for mobile and web-based applications; especially for single-page applications. As one of the most flexible, scalable, and adaptable JavaScript frameworks, ReactJS is a popular front-end JavaScript library in the market. Their ReactJS migration is very common among developers. With this JavaScript library, coders are enabled to build large-scale applications without the need to reload the page where the data is reflected in real-time. ReactJS efficiently manages the view layer of mobile and web apps.

Moreover, as a lot of JavaScript frameworks and libraries are currently dominating the development arena, ReactJs emerges as one of the most adopted and used JavaScript framework, which deals with View in MVC. 

History of ReactJS

Invented by Facebook in 2011, the sole aim behind creating ReactJS was to build a JavaScript-based library that eliminates the challenges faced by coders while working with JavaScript. Subsequently, ReactJS simplifies the mobile as well as Angularjs web app development and fosters a comfortable user experience (UX). 

Over time, Facebook integrated this new library into the Newsfeed of its web-based social media platform, and eventually declared React JS as an open-source framework in 2013. However, by that time, ReactJS had already gained a mass following from developers across the world in creating single or large-scale applications, who were just waiting for an efficient and simple JavaScript-based library.

Then came 2015, when this transformative technology was released as a hybrid mobile app development framework by the engineers at Facebook. Soon, ReactJS was everywhere; every developer's community and companies that prefer the mobile-first strategy are migrating their current code to React JS development framework. 

However, as ReactJS is a lightweight JavaScript library, it only supports user interface components; for further building the entire architecture of the code, it has to be integrated with other tools, libraries, frameworks, and technologies. 

Beneficial Features of ReactJS Migration

Virtual Document Object Model (DOM)

This is the main feature of ReactJS, which enables scalable and fast applications’ development. In React, it is known that for every DOM there resides a corresponding ‘Virtual DOM Object’, as the representation of the DOM object. Whenever any alteration occurs in the web application, the complete user interface is re-rendered in virtual DOM, enabling developers to compare the new DOM and previous DOM representation. Later, the original DOM updates only the components that have changed, leaving the other component untouched. 


In React, everything is component; every section of the mobile or web application visuals is enclosed inside a self-contained module called a component, where each component has a specific logic. This logic is written in JavaScript, not in templates, empowering coders to simply pass the data through their app and keep the state out of the DOM. 


JavaScript XML (JSX) is a syntax extension that describes how the web or mobile app user interface should look like, similar to HTML. Using JSX, coders are free to create React UI blocks and React components very easily and quickly; they only need the HTML syntax. Besides Virtual DOM, JSX is another main feature of ReactJS migration. 

React Native

A custom rendered for React, just like React DOM on the web, React Native makes use of native components rather than web components as building blocks. For any developer to begin with React Native, they need to be aware of the basic ReactJS concepts such as the aforementioned JSX, components, states, and props. Coders then need to move onto more advanced concepts such as native components. 


As mentioned above, React is known for creating intuitive and dynamic user interfaces for web and mobile applications. As it focuses only on the View part of MVC, ReactJS is proficient in creating simple, declarative views for each state in the application, making it easier to read and debug.
