Read it in 5 Mins
In this article
Node.JS is a JavaScript runtime engine used to develop real time applications. It is an open source, cross-platform runtime environment that allows you to develop client-side as well as server-side applications. It is fundamental, and the platform acts as a prerequisite to installing your machine. For more details on its properties, you can visit Node certification to strengthen your base.
JavaScript was always a browser/client side programming language that runs on browser only because it was understood by browsers only. The browser uses JavaScript Engine to interpret into machine code to execute completely.
There are different types of browsers like Chrome, Mozilla, Opera. Browsers interpret JavaScript code according to browser configurations and JavaScript Engines.
Spider Monkey was the first JavaScript Engine developed for Netscape and Chrome uses V8 JavaScript Engine. But JavaScript is later expanded for Mobile, Desktop or Server to build under v8 runtime environment and Node.JS
Node.JS is not any programming language or a framework. It runs JavaScript written code into a standalone machine code. It helped JavaScript developers to build stand-alone scalable full-fledged applications.
Node.JS is actually the JavaScript Engine that runs JavaScript written code and allows both client side and server side development .
Node.js comprises of certain key features:
- Node.JS comes with high efficient full stack development than other programming languages like C++.
- Node.JS allows smooth sync and alignment of front end and backend.
- Node.JS is light and scalable.
- Concurrent request processing, single thread event loop, non-blocking input-output model makes Node.js CPU favorite and highly processed at backend.
- Node.js has a rich packaged ecosystem that amplifies every strength of JavaScript to its best.
Node.js Latest Version (Current Version)
Node.js is the robust hero of development to build efficient and scalable real-time applications. The landscape of node.js takes you to the different rocks of versions and releases. The nodejs versions keep growing for better functionality and better operability.
When you visit Node.js official website you find two different paths to choose from :
LTS or node its version, also known as Long Term Support version, with stable and safe features are recommended for long term support . The current version includes an experimental phase with a high probability of bugs and errors.
The above image varies in node js according to the versions that is installed either on Windows or macOS.

Every version of node.js comes with different features or adding or removing some features for data-driven efficient development. Node.js versions look like x.y.z where x represents the most significant changes, and the rest represent the minor changes.
Generally, even-numbered node.js versions are recommended for development and deployment into production environments, referred to as node stable versions, and odd numbered node.js versions are better suited for library maintenance. Also, version 7.0.0 is the npm stable version, and npm-check-update is the command line for the npm major update. version.
Node 17
Overview
node.js npm versions release schedules with the time interval of six months where the new version becomes the current npm version with the experimental zone. The old version becomes the active LTS recommended but bug-corrected by developers with long term version in use. Also npm –v is used for the npm current version on the terminal.
Remember, nvm is the node version manager that allows version-switching but npm is a package manager that allows to install third-party software to build node js applications.
Node JS version 17 is no longer the Current version released in October 2021 but Active LTS comes with major responsibilities and add-on features.
Before exploring more into the key features, nvm is used to replace node js older version and update node.js version.

The code sample to upgrade to Node 13 VERSION looks the same as Node 15 and node 16 above.
Node 12 & Earlier
Node 12 and earlier versions are on the verge of deprecation and are not being now generally used more often in development due to the new versions and their features add-on. The older features have gradually become redundant and are not in much use now due to older syntax tactics.
The current stable version of node.js to use is Node 16 with active LTS support.
Which Version of Node JS is Best?
The Node.js versions have a list of variations making it confusing and ambiguous for developers to choose which version to install, reinstall or upgrade. It is always advised to install the current version that works best for your project and development requirements.
The different environment managers differ different node js versions to be installed.
But the official documentation suggests to always use even numbered versions that are labeled as Recommended for most users on the download page on the official site.
Even node versions like 16.x.x LTS, 18.x.x LTS are used for learning and deployment.
Choosing your node-version is a cyclic process of upgrading or downgrading the required version compatible with your requirements.
We should try to avoid current versions because even though they are advanced to work on but without the LTS label, they are less reliable and more experimental. Check out the KnowledgeHut’s Node Certification course to strengthen your node.js skills with real time projects.
Conclusion
The LTS node versions are the most often recommended for development and learning. You can find the latest LTS support on the official Node.js site.
The different node.js comes up with different versions, releases, checks and updates, but it is always advised for developers to use LTS landscape for stable support and fewer bugs. But if we try to experiment more with open-source we should test current versions to find out ambiguity or bugs for a future fix.
The Node.js is a runtime environment behind the execution and scalability of full-fledged JavaScript applications. The extended steps can be taken with a Full Stack Developer course to build real projects.
