React is a JavaScript-based UI library developed by Facebook. It is a flexible, declarative, open-source JavaScript library to develop simple and scalable frontend interfaces for single or multi-page web applications. While handling rapidly changing data, React.js allows the developers to create reusable UI components and generate interactive UI/UX developments to enhance the real-time user experience. Reasons to choose react.js for front-end development:

  • 1

    Easy to create dynamic web applications because it offers more functionalities and less coding

  • 2

    ReactJS uses Virtual DOM that compares the components of the previous state and updates the ones that were changed in the Real DOM

  • 3

    React allows unidirectional data flow which makes it easier to debug errors and know where a problem has occurred in an application

  • 4

    Components are the building blocks of any ReactJS application and their reusability makes it easier to develop applications faster

  • 5

    In a Model-View-Controller, ReactJS is the View responsible for the look and feel of the application

  • 6

    Facebook provides a browser extension that makes it straightforward and easy to debug React applications

  • 7

    All the activities stay modular and quick with ReactJS’ one-way data binding

  • 8

    React.js combines JavaScript components and basic HTML with some beneficial additions which makes it easy to learn


MERN stack is a JavaScript stack used for easier and faster development of full-stack web applications. MERN stack comprises all the leading JavaScript-based technologies like MongoDB, Express.js, React.js, and Node.js providing end-to-end development process of web applications.

  • M stands for MongoDB, an open-source, cross-platform database program that is a NoSQL database system

  • E is for Express.JS, which is an effective middle layer to develop RESTful APIs and dynamic web apps

  • R stands for React.JS and is used in developing a client-side JavaScript framework

  • N stands for Node.JS. It is for enhanced back-end services and develops scalable web application

MERN stack encapsulates database, server-side and client-side technologies for easy development of mobile and web applications.



MERN stack development has technologies that align with the current trends in the industry for building feature-rich and advanced applications that are scalable and responsive. MERN stack components are used to build a full-stack project with an attractive interface for users to interact. Three-tier MERN architecture enables the users to navigate through the pages and respond to actions quickly and smoothly.

  • MERN provides an end-to-end development environment with a full-stack development environment

  • As every line of code in MERN is written in JavaScript, developers can easily integrate and work with various libraries and frameworks for the client-side or server-side

  • It has a collection of dynamic user interfaces readily available with the library to execute code quickly

  • MERN makes it easy for JSON data to flow from front to back while making it faster to build and debug

  • MERN follows Model View Controller (MVC) architecture for easy development of workflows

  • MongoDB can easily be integrated with Node.js to manipulate, store and represent JSON data in web apps

  • HTTP responses and requests are encapsulated by Express.js to plan the URLs for server-side mapping


React.js enables developers to create an application that can change the data without reloading your page. Given the wide range of technology stacks, MERN is growing rapidly popular as an integral part of Full Stack Development. However, it is best suited for cloud-native JSON applications that require dynamic web interfaces such as interactive forums, workflow management, and social products. There are some additional core features of ReactJS that needs to be addressed and they are:

  • Creation of Dynamic Web Applications

    Before the development of React.js, a lot of complex coding was required. React uses JSX which has a particular syntax and lets you render subcomponents with HTML quotes and tags. It also supports creating machine-readable code and mixes components with an individual variable file.

  • Mobile Application Development

    React.js facilitates and provides design patterns for web and mobile application development. Using React and other JavaScript we can build high-end user interfaces that are supported by iOS and Android systems.

  • Code Maintenance

    React.js makes it easier to define and manipulate the objects that are used in dynamic web applications. React.js’ major advantage is to reuse components which in turn will provide better code maintenance.

  • Ensures Faster Rendering of Virtual DOM

    For building high-load applications, Virtual DOM was introduced. DOM (document object model) created bottlenecks due to its tree structure and even small layers could make drastic changes. As React uses Virtual DOM, it can be used for heavy-loaded and dynamic solutions.

  • SEO-Friendly Features

    During common search engine failures, React.js runs on a server, renders, and returns Virtual DOM to the browser. ReactJS doesn’t require JavaScript to render the content on the page. It is achieved by Server-side Rendering (SSR.)
