Unveil Key Features of React JS for Web & Mobile App Development

A lot of JavaScript frameworks and libraries are available in the tech world. The more options create more confusion in making a decision. Same happens to businesses when developers discuss the varied JavaScript frameworks with them. Especially, when the entrepreneurs are not tech savvy, selection of the right JavaScript framework becomes a challenge for them.

Have you ever gone through such a dilemma?

If yes, then I can help you partially in picking the most effective JS framework as per the specific requirements of your web and/or mobile app development.

Among all the popular JS frameworks React JS is widely preferred by developers and businesses due to various reasons. One of them is its power packed feature set.

Well, we won’t directly jump to the features part. Let’s explore React JS technology as a whole by having its definition, its inception to journey till the time and last but not least its excellent features that build amazing web and mobile applications.

What Is React JS?

React JS is an open source and component based JavaScript library used for creating dynamic and interactive user interfaces, especially for single page applications. It is highly flexible, declarative and efficient for developing scalable, simple, and fast front-end for web & mobile applications. React JS effectively handles the view layer of mobile and web app.

It allows developers to create intuitive, interactive and engaging applications with minimum coding and the best rendering performance. With the JavaScript library, developers can build large scale applications without reloading the page where data reflect in real-time.

Growth of React JS in as a JavaScript Framework

React JS is invented by Facebook’s software engineer named Jordan Walke in 2011. He wanted to create a JavaScript-based library that simplifies the app development and fosters a more comfortable user experience.

Facebook integrated the new library in the Newsfeed of its web-based application.
The library is declared as open-source on March 2013. Till that time, React JS gained immense popularity in developing single page and large scale application by performing view rendering work.

In 2015, the technology is released as a hybrid mobile app development framework by Facebook engineers. React JS soon adopted by the developers’ community and companies that adhere to the mobile-first strategy. Since then, React JS started competing with the other JavaScript frameworks and rules in the tech world.

As React is a lightweight JS library that supports only UI components it has to be complemented with other tools, libraries, frameworks or technologies in order to build a complete architecture.
With the continuous enhancement, React JS web development offers numerous possibilities such as real-time updates, server-side rendering, different rendering target such as Android, iOS and so on.

Let’s build high performing large scale and single page application using the power packed features of React JS.

Features of React JS

Virtual DOM

Virtual DOM (Document Object Model) is the key feature that enables React JS to build scalable and fast applications. It contains a memory reconciliation algorithm that helps React to create a representation of a web page in virtual memory. So Virtual DOM is the representation of original DOM.

Whenever changes occurred in the web application, the entire user interface is re-rendered in the Virtual DOM representation. Developers can check the difference between new DOM and earlier DOM representation. Later on, the original DOM will update only those components that have actually changed and not all components of virtual DOM. Thus, it helps in developing the app faster with the wastage of memory.


JSX stands for JavaScript XML. It is a syntax extension that describes how the web or mobile app UI should look like. The markup syntax closely resembles with HTML. It is a combination of JavaScript and XML.
With JSX, developers can build blocks of React UI, and react components easily by making the syntax of HTML. It is identical to the HTML the programmers will inject in the web page. Thus, JSX is the best feature offered by React JS as it allows web developers to go for an easy way out.

One Way Data Binding

One way data binding does not permit developers to edit any properties of the React JS component directly. With the help of callback function, they can modify the property. This process is known as one way data binding.
React JS follows one-way data binding or unidirectional data flow that gives better control throughout the application. Additional features are required to manage the data flow that comes from another direction.
As React components are immutable, the data within them cannot be changed. Using Flux, developers can keep data unidirectional and makes the application more flexible that improves its efficiency.

React Native

It is custom render for React that uses native components rather the web components just like react as building blocks. To get a profound understanding of React Native, one should need to know about the basic React components. Such as stats, conditions, components, props, and JSX.
Once you have clarity about React, you need to explore the information specific to React Native to learn about the native elements. Apart from making the React code compatible with iOS and Android platform, React Native provides access to the features these platforms offer.


As we discussed before, React JS creates an intuitive and interactive user interface for mobile and web application. React effectively renders and updates the right elements when the data changes. The library creates simple views for every state in web applications. Declarative sight creates the code that is simpler to debug and more readable.


React JS framework is based on components. It contains numerous components that create a user interface of web applications and each component is designed with a specific logic. The logic is written in JavaScript instead of templates, so developers can easily pass the data throughout the application and keep the state out of the DOM.

React JS components play a key role in defining interactions and visuals in the applications.
