Is Node.js Really Necessary? A Case-by-Case Overview

What do you think about implementing JavaScript on the server? Here’s where you need to be. However, Node.js goes far beyond mere Javascript on the server, as you’ll discover in the Node JS training and learning path. Node encompasses a very wide range of topics. A vast subject could not be covered in a finite number of topics. Google’s V8 JavaScript engine, the libuv platform abstraction layer, and a JavaScript core library make up Node.js, which is a packaged jQuery implementation. Aside from these features, you should also note that Node.js’ creator, Ryan Dahl, was inspired by applications like Gmail to create real-time websites with push capabilities. Essentially, it introduced the idea of event-driven, non-blocking I/O to developers.

Why Should I Use Node.js?

  • Popularity of Node

JavaScript is also one of the most popular programming languages in the world and is a breeze to master (though I will admit that it requires a lot of practice). It’s a server-side implementation of JavaScript. Platform-wise, Node.js is among the most popular server platforms currently available, and it is the foundation for the MEAN stack. Having knowledge of Node means you will have good employment prospects.

  • A Powerful Node

The Node.js framework is asynchronous and uses non-blocking I/O. Node applications that behave well do not experience significant issues as JavaScript is a single-threaded language. Asynchronous programming is commonly done in web applications using JavaScript callbacks, Promises, and async/wait methods. Your server can now offer this experience thanks to Node. As a scalability weapon, Node also has the event loop. The event loop is used to make I/O requests transparent to threads, allowing asynchronous programming techniques to be implemented.

  • Node Is A Community

A large, active, and open community exists for Node.js. Node community members usually share code through the NPM registry, which includes plenty of free code, as well as documentation and source code for your apps.

  • One-of-a-Kind Platform

Node.js is not a silver bullet for developing web applications, and this is really what it means. Platform-like, it serves a purpose. The importance of understanding this cannot be overstated. You definitely shouldn’t use Node.js for computations that consume a lot of CPU power; its advantages will be almost nullified. A Node application really shines with its ability to handle many simultaneous connections at high throughput, meaning it will have scalability.

  • Prerequisites

For this Learning Path to be as helpful as possible, you should be familiar with JavaScript. The same goes if you’re not, but have experience with languages like C++, Java, C#, PHP, Python, and so on and so forth. Learning Paths are not for those without any programming experience.


From goals and ambitions to sweet spots and pitfalls, we’ve discussed Node.js theoretically and practically. 99% of misuses of Node occur because of blocking operations because they are at the root of all issues. When your use cases do not require CPU intensive operations or resource blocking, you can still take advantage of Node.js’ benefits and create fast and scalable network applications. So, instead of waiting and thinking, just go and take Node JS training and apply it in the real world to fulfil your ideas. The real-time web is here.
