React vs. Node.js: A Comparison of the Two Best JavaScript Tech Stacks | by SharmaGourav | Dec, 2022

One of the few programming languages widely used among the other tech platforms is JavaScript, but several JavaScript frameworks are also available. Although React vs. Node.js remain the most popular option, it might be challenging for programmers to decide which is best.

42% of programmers and creators of intelligent applications worldwide utilize this platform, as per Statista.

React would be a Javascript framework, whereas Node.js is a framework. As a result, if you are creating a program with Node.js, there is a likelihood that it will also use React, and conversely.

Facebook developed the JavaScript library React for building user interfaces with components.

Components allow for code reuse and efficient code organization. To track component changes, React js development company leverages the Virtual DOM.

It merely modifies the virtual DOM, avoiding costly re-rendering whenever some new data arrives.

Origin of React

Once the Facebook newsfeed group encountered difficulties handling and preserving DOM changes, react was born. The user interface is challenging to utilize since the DOM is sluggish.

Makers only need to build one app. Even though at least 95% of a code is cross-platform or accessible on both iOS and Android phones, two apps are ultimately created.

React, a library created by Facebook was created to address the issue. It is quick and flexible for creating user interfaces and solves DOM update problems.

Who & When Did React Create?

The initial React launch took place around May 29, 2013. Jordan Walke, a Facebook employee, developed the idea.

He invented the concept and discovered a solution to the performance problems with DOM changes.

Following the resolution of this issue, Facebook decided to make React open access and a collaborative effort.

What Are the Core Features of React?

Its primary attributes are:

1. React is based upon the virtual DOM, which uses a lightweight approximation of the real DOM to reduce costly re-rendering. React only updates the appropriate fields in the actual DOM whenever new information is available in elements. In this manner, time is conserved, and existing HTML components are reused to the greatest extent.

2. Parts — Elements are modular, reusable units of code that make it simple to create and manage complex applications. These parts can be further broken down into smaller or “child parts.”

3. JSX would be a JavaScript syntactic extension that resembles HTML in appearance. Instead of using layouts or web views, it enables you to build your markup in JS. As a result, since everything is in one location, it is simpler to maintain track of the material on the website.

4. Data binding that only allows one direction of flow. When the status changes, the user interface immediately adjusts. Using straightforward methods, you can cause UI updates whenever an application condition changes.

Various online applications, especially new projects, ongoing projects, and mobile apps, can employ React.

Any UI that needs status updates may use it ideally. React is now used by Yahoo, Airbnb, Imgur, Instagram, Netflix, Dropbox, and Sony, among other businesses. you can find the comparison between react and react native

A JavaScript run-time platform that is open-source and cross-platform for use outside of browsers is Node.js. It is small, effective, and ideal for dispersed devices’ data-intensive real-time applications.

Origin of Node.js


When the Joyent team ran across issues with JavaScript on the server side, Node.js was born. The usage of JavaScript across dispersed platforms and the integration of C++ proved to be complicated.

The V8 JavaScript engine from Google — the same JavaScript algorithm that drives the Chrome browser — was then utilized to construct Node.js by Ryan Dahl, a programmer engaged in most of their products.

He used non-blocking I/O to manage several connections at once effectively. Following Joyent’s 2009 open-source release, many businesses now employ Node.js to create web services.

What Are the Core Features of Node.js?

Among the key characteristics are the following:

  1. Events — Node.js is lightweight and efficient because it uses an event-driven monitoring system based on the “process” component. Node.js can develop fast web servers because of this event-driven design.
  2. Single-Threaded — Node.js only supports one process since it is single-threaded. When several requests run simultaneously, they will stand in line for a response (unless there are many CPU cores).
  3. Asynchronous — To properly manage many connections, it adheres to non-blocking concurrent input/output. Think of an online shopping platform as an illustration. If Node.js did not enable asynchronous calls, requests for placing orders would be halted until the consumer cleared out and the item got placed in the basket.
  4. non-blocking input/output has contributed to Node.js’s performance, but it also provides additional benefits. Assigning concurrent queries to a JavaScript procedure enables developers to manage them more conveniently. It produces cleaner code as a consequence.

Where Can Node.js Be Used? Who Uses It, and Why?

To create web servers, real-time services like chat and information exchange, and APIs (application development interfaces) that enable mobile apps, you may engage Node.js engineers. PayPal, Walmart, Uber, and, therefore, more businesses presently use Node.js.

Use Cases for Node JS

To assist you in comprehending the kinds of apps you may create with Node JS as well as decide if it’s the right technology for you, the following use examples are provided:

  • Real-time chats: Picture applications for video conferencing and instant messaging. Node JS is recommended for growing real-time chat systems since it permits continual two-way communication.
  • Highly Scalable Programs: Since the application is JavaScript-based, Node can swiftly pull it. Because of this, Node JS excels at rapidly handling growing demand and scaling.
  • Hosting for Single Page Applications (SPAs): When utilizing SPAs, Node JS is a robust asynchronous technology that speeds up the transfer of information. Furthermore, Node’s non-blocking I/O is quite good at managing several concurrent applications.

React JS use cases

Remember that Facebook initially developed and managed React? (Now Meta). Services like Uber, Yahoo!, Netflix, and even the New York Post all use it.

Here are a few other use cases:

  • Reporting tools or Visual Analytics Tools: React JS uses reusable components, sophisticated algorithms, and D3, a visual analytics tool that is very useful for BI and analytics tools.
  • Social Platforms: SPAs enhance speed, but data synchronization with the user experience is challenging, and using HTML templates is wasteful. All of these problems can be solved with React JS.
  • Cross-Platform Mobile Applications: Since you would use the same programming on both devices, cross-platform design is often more time and money efficient than native development.

Node.js is ideal for building scalable server-side web applications, such as video streaming platforms.

When you want to create a project with changeable states, such as dynamic interfaces, buttons, and so forth, React.js is the perfect fit.

Despite the difference between react js and node js, a project can employ both react and node js technologies. Construct the back end of the web application using the Node.js framework and the front end using React.js.

There is a sizable and vibrant industry that supports both React and Nodejs. Depending on the demands and specifications of your project, you can select one or the other.

Both frameworks are available for use simultaneously for your website development requirements. Because it was created with both Node js only for the back end and react js for just the front end, Netflix is the most remarkable illustration for this use case.
