With the increasing acceptance of JavaScript, Node.js has gained its technique of inviting countless companies universally and of being a robust technology for numerous developers and technology professionals. 

After its introduction in 2009, it eliminated the requirement for diverse languages by permitting a single language app development.  This JavaScript tool aided several popular companies to use Node.js and develop countless completely functional applications.

Though Node.js is mostly used to develop web applications in actual time, mobile app development is also feasible.  This is possible due to the Node.js ecosystem and majorly due to its biggest package manager ecosystem in the globe – NPM.  Let’s understand the concept of Node.js and find out which renowned companies are utilizing this dynamic technology.

Introduction to Node.js

Node.js is an open-source JavaScript runtime environment that performs JavaScript code separately outside a browser.  Node js allows developers to utilize JavaScript to transcribe command-line tools.  For server-side scripting – functioning scripts server-side to yield robust web page content before the page is directed to the user’s browser. 

Subsequently, Node js signifies a ‘JavaScript everywhere’ prototype, uniting web app development in a single programming language, instead of diverse languages for server and client-side scripting.

Nevertheless, Node.js is the typical filename extension for JavaScript code, the term ‘Node.js’ does not refer to a specific file in this setting and is just the name of the product.  Node js is a cross-platform and has an event-driven pattern that is capable of asynchronous I/O or non-sequential I/O. 

These architecture selections have a purpose to enhance throughput and scalability in web apps with several input/output processes, along with real-time web applications, for example, browser games and real-time communication programs.

A Brief

Node.js is a cross-platform runtime environment for building server-side and networking web applications.  These applications are transcribed in JavaScript, and can function within the Node js runtime on Microsoft Windows, Linux, and OS X.  It also offers a rich library of numerous JavaScript modules which streamlines any web application development utilizing Node js to a great amount.

Node js is simple to get started and can be employed for prototyping and responsive software development.  It provides fast and extremely scalable services.  It exercises JavaScript everywhere so it is simpler for a JavaScript programmer to develop back end services utilizing Node js.  Its source code is cleaner and consistent and has a large ecosystem for open source libraries.

We often come across the most prevalent question: ‘Is Node.js different from Angular?’  From one of our blogs, Node.js vs Angular, we can ascertain that Node.js is primarily utilized to build server-side apps.  Whereas, Angular is preferred to develop single-page client-side web applications.


Developers choose to employ Node js because it can easily scale up the application in both horizontal and vertical routes.  Node js function on the V8 engine built by Google.  Event loop in Node js manages all asynchronous processes so that it performs like a fast suite and all operations can be done rapidly like writing or reading in the database, file system, or network connection.

According to the Stack Overflow survey in 2020, from the following statistics, we can see that Node js takes the top spot.  In Node js, the HTTP request and its response are ascertained as two distinct events.  They are the data stream; so while you process any file at a given time of loading it would decrease the overall time and will create it quicker when the data is offered in form of transmission.  It also permits you to stream any video and audio files at a lightning speed.
