What is JavaScript?

Programmers use the JavaScript programming language worldwide to create dynamic and interactive web content, such as applications and browsers. The JavaScript programming language is the most popular in the world; 97.0% of all websites use it for client-side programming. Client-side languages are those whose actions take place on the user’s computer rather than on the server.

JavaScript is versatile for diverse applications, like software, hardware controls, and servers. JavaScript is best known as a web-based language because it’s native to the web browser.  

JavaScript makes web pages vibrant. Before JavaScript, web developers created web pages with Hypertext markup and CSS. HTML and CSS are inefficient at creating stationary pages that can be designed but not interactive. Some of the most widespread websites are made with JavaScript, involving Google, YouTube, and Facebook.

What is Node JS?

Node JS is an open-source, cross-platform, backend JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser designed to build scalable network applications.

Node JS is a server-side, also known as the supply side. It is a technology platform that enables web publishers to manage their advertising and promotional inventory. 

Node JS is an open-source, cross-platform, backend JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser designed to build scalable network applications.

The audience believes it is one of the easiest methods to make the backend of a website. 

Features of Node JS

The features of Node JS are diverse and are mentioned below.

  • Non-synchronous and Event Driven − All APIs (APIs are mechanisms that enable two software components to communicate with each other utilizing a collection of interpretation and formalities) of the Node JS library asynchronous is non-blocking. Node JS-based servers by no means wait for an API to restore data. 
  • Moving it to the following API server calls and receiving a notification mechanism from Events of Node JS benefits the server to receive a response from the previous API call.
  • Quick − Being built on Google Chrome’s V8 JavaScript Engine, the Node JS library is very rapid in code performance.
  • Single Threaded – It is single-threaded with an event loop but extremely scalable and can handle large amounts of data. Contrary to traditional servers, which create limited threads to handle requests, the event mechanism makes the server highly scalable and non-blocking. Unlike traditional servers such as Apache HTTP Server, Node JS uses a single-threaded program that can handle a much greater number of requests.
  • No Buffering − Node JS applications never buffer any data. These applications output the data in chunks.
  • License − Node JS is released under the MIT license. 

Uses of Node Js

A Node.js web server application that requires I/O bound to use this module. In most cases, the network, filesystem, and database I/O take most of the time. Increasing hard disk speed and network connection improves the whole functioning.

Node.js is most appropriate for this type of information technology. All I/Os in Node.js are non-blocking, allowing other requests to be served. Node.js is also used in Data Streaming Applications, Data Intensive Real-time Applications, JSON APIs-based Applications, and Single Page Applications. However, Node.Js programming language should not be used in CPU-intensive devices. 

React.Js and React Native 

Both technologies are widely popular today on websites. A conversation examining ReactJS vs. React Native is common in app development. However, even experienced developers can be vague on the nuances in the React vs. React Native argument.

React Js is concerned with web development, whereas React Native performs well on the mobile framework. 

React Comparison 

React JS is where developers can use a better UI ( user interface) to improve the user experience and attract them. It also offers users better security and enhanced features as it affects the animation. 

The Document Object Model (DOM) bases are of React JS, and code is rendered from there. React JS has a library at its base, which can be utilized to develop a great user interface performance.

React Native, on the other hand, is where the entire framework is developed regardless of IOS or android. Many developers may not use it because of the low security it offers to fulfill clients’ demands. Furthermore, the animation and its functionality are not up to the mark. React native is a function derivative, and react native APIs are used in mobile applications. It also doesn’t have a library. 

 Features of React JS. 

  • The virtual Document Object Model (DOM) in React JS enhances the execution of applications. Initially, React JS developed an in-memory cache configuring variation that was then renewed in the DOM.
  • React JS allows you to create dynamic applications: React Js is a good choice if you want to create a user-friendly network application with lesser coding lines.
  • The JavaScript syntax feature is convenient when describing your application’s user interface.
  • Data binding with one-way functionality: This feature helps reduce errors. If a small change is made to the parent component, you don’t need to rework the entire thing. With React JS, code stability was achieved that wasn’t common before and made maintenance easier.
  • Framework with a component-based framework: Another exciting aspect of React JS is its modular architecture. In applications, you can pass data throughout, excluding any changes to the DOM.
  • You can still use HTML: React JS; the best part is that it provides library access while enabling developers to use a hypertext markup language for coding. 
  • Since its beginning, React JS has always been a reliable core for skilled developers who have enhanced it through additional libraries and extensions. 
  • Since its inception, React JS has always been a trusted hub for seasoned developers who have improved it through further libraries and extensions.
  • The real-time view of all the changes gives you a better idea of your progress. Developers can preserve time and money by utilizing the same code for different components.
  • SEO-boosting effectiveness: React JS supports SEO optimization by allowing indexing of a site to occur faster. Thus, SEO optimization contributes to the website’s success, allowing the content to be indexed by the server. More leads mean more revenue for business owners and web developers.
  • The fastest loading time: React JS guarantees one thing to the users a lower bounce rate. Page analytics can be crucial in examining React vs. React Native differences. The user heads to a faster-loading page when a web page takes too long to load. There are various types of advantages to using React JS.

Uses of React Js.

React JS is used by a lot of companies like Facebook, Netflix, Uber, The New York Times, Airbnb, etc. Dropbox, Instagram, and other platforms utilize it too.

Node Js Vs. React Js 

Choosing Node JS or React JS seems like a debatable topic as many may think of choosing either of the programming languages to create the best servers for the users and the clients as it’s a branch of one of the programming languages known as Javascript. 

However, the truth is that any web development department specializing in Javascript must use both sub-programming languages because both are important. It is necessary to use both of them because then only the final product will be prepared. 

Javascript is widely used, has gained popularity over time, and has changed the dynamics of web and servers. React js will provide a better front end, whereas react is used for better backend purposes. Hence, combined then only provides the best outcomes. 


Technology is fast-moving, and as new technologies disrupt the market, the old technologies exit as they become obsolete. Javascript, for many web developers, is a conventional coding language, but because of the features it offers to the various web development departments, it is popular and allows audiences to witness the best of the outcome. I.e., Netflix is the staple source of entertainment, so is the case with Facebook, and all such platforms have been made through Node Js or React Js, one way or the other.

Hence, it isn’t easy to decide which one is better or to do a versus analysis of both the coding languages.
