JavaScript is the most popular programming language that is used as a client-side development tool almost 95% of websites. You must be thinking about what about server-side programming languages?

With the introduction of Node.JS – only Javascript-based back-end framework, Javascript has become an all-purpose full stack development language, Whereas Angular, Vue and React are front-end frameworks or libraries.

Let’s have a look on Node.JS with its Pros and Cons:



An open-source runtime environment for JavaScript that is based on Chrome V8 for chromium browsers. Node.JS allows your programs to be written in JavaScript and to be executed on the server.

A part of popular MEAN and MERN – NODE, a Javascript centered technology stacks that covers the entire web development pipeline.

Node.JS is firstly written in 2009 and the purpose behind that is to create dynamic web pages before they are sent to the browser and as the day passed it became one of the most used tools in back-end development.

There are a number of reasons why NodeJS became a standard for enterprise companies like Uber, Netflix, and eBay. Few of the programming languages can boast a rich package ecosystem as Node.JS.

Node.JS inherits a number of Javascript features that include its libraries and this is why front-end developers like to learn it very quickly.

Pros of Node.Js:

  • When compared to JAVA or C, Lightweight JavaScript achieves high performance with just fewer line code.
  • For Javascript full-stack development Node.JS has opened the doors, by allowing engineers to use its features and libraries after inheriting the merits of JavaScript programming.
  • As the single language used on both sides of the application, it became easy to keep frontend and backend in sync.It considered as fastest for Chrome’s V8 engine.
  • Node.JS used to compile JavaScript into machine code instead of using an interpreter.
  • The reason Node.JS is favorite among microservice architectures is that Node.JS is highly scalable and lightweight.
  • It fits well for designing architectures with the help of Node modules that represent the building blocks of Node.JS functions.
  • The non-blocking input-output model that allows processing number of requests at a time and these make Node.JS highly efficient to process multiple requests with less CPU usage.

Cons of Node.Js:

  • As it uses a non-blocking input-output model for processing requests hence it’s considered a single thread by nature.
  • NPM registry seems to be quantity but not quality driven.
  • As the core products prove to be stable and well-tested other rest of the NPM registry is badly documented and poorly structured. There is something not uncommon for open source projects.
  • Another major con is the lack of experienced JavaScript developers that work with backend.
  • The major drawback we can consider is that whenever there is a heavy-computation request Node.JS setup block on the other request on the thread and cause an overall delay.

Node.JS is a lightweight tool and powerful for full-stack development. All tools come with some weakness and for Node.JS we can say performance bottleneck for CPU heavy operations but it has a lot of good things like the project is strongly supported by the enterprise giants who invest in its development as well as the community also.

You must be thinking what about others ReactJS, AngularJS, and VueJS, no need to worry, here we have a detailed comparison of all three of them.

Let’s Have A Look At Detail Comparison Of ReactJs, AngularJs, and VueJs:

Comparison Of ReactJs, AngularJs, and VueJs




Type A Framework  A library that builds UI Library
Founders  Powered by Google  Managed by FaceBook A former Google Employee has created 
Written In TypeScript  JavaScript  JavaScript
Language Preference Use of TypeScript  Use of JSX – JavaScript XML HTML templates with JavaScript
Initial Release Sep – 2016 Mar – 2013 Feb – 2014
Types of Application  Native Apps, Hybrid apps and Web apps  SPA and Mobile apps Advance SPA and start supporting Native apps
Model Based on MVC – Model, View, and Controllers Virtual DOM – Document Object Model Based on Virtual DOM – Document Object Model
Learning Curve Steep Learning Curve A bit easier than Angular  Small Learning Curve
Developer – Friendly Use a structure-based framework If you want to have a flexible development environment. If you want to have separation of concerns.
Popularity  Widely popular among developers  More than 27,000 stars added over the year During the year on GitHub, more than 40,000 stars added.
Companies Using Google, Forbes, Wix, and Facebook, Uber, Netflix, Paypal, Walmart, Reddit, and others. GitLab, Alibaba, Baidu, and others.
Ideal For  If you want feature-rich applications and focus on large-scale For native-rendered apps for iOS and Android and also for Modern web development Ideal for single-page application and web development

All these are pretty fast and production applications are running with all three of these.

With this, I’m not declaring anyone as a winner but I can encourage you all to have a look at this at your own. For some of the applications, AngularJs will be good, for some of them may be ReactJs will be the best.

We can say there is no better worse one as they follow different approaches and philosophies.

So, if you go through all these Node.Js will be still relevant in 2019 as in the market lot of frameworks and libraries but I can encourage you to dive into all of them and select the best one as per your preferences to create great applications.
