It’s easy to get started and can be used for prototyping and agile development

It provide fast and highly scalable services

It uses JavaScript everywhere so it’s easy for a JavaScript programmer to build back-end services using Node.js

Source code more cleaner and consistent.

Large ecosystem for open source library.

It has Asynchronous or Non blocking nature.

Easy Scalability

Developers prefer to use Node.js because it is easily scale the application in both horizontal and vertical direction. We can also add extra resources during the scalability of application.

Real time web apps

If you are building a web app you can also use PHP and it will take the same amount of time when you use Node.js, But if I am talking about building chat apps or gaming apps Node.js is much more preferable because of faster synchronization. Also, event loop avoid HTTP overload for Node.js development.

Fast Suite

NodeJs runs on the V8 engine developed by Google. Event loop in NodeJs handles all asynchronous operation so NodeJs acts like a fast suite and all the operations can be done quickly like reading or writing in the database, network connection or file system

Easy to learn and code

NodeJs is easy to learn and code because it uses JavaScript. If you are a front-end developer and have a good grasp on JavaScript you can easily learn and build the application on NodeJS

Advantage of Caching

It provides the caching of single module. Whenever there is any request for the first module, it gets cached in the application memory so you don’t need to re-execute the code.

Data Streaming

In NodeJs HTTP request and response are considered as two separate events. They are data stream so when you process a file at the time of loading it will reduce the overall time and will make it faster when the data is presented in the form of transmissions. It also allows you to stream audio and video files at lightning speed.

Hosting

PaaS (Platform as a Service) and Heroku are the hosting platform for NodeJS application deployment which is easy to use without facing any issue.

Corporate Support

Most of the well known companies like Wallmart, Paypal, Mirosoft, yahoo are using NodeJS for building the applications. NodeJS uses JavaScript so most of the companies are combining front-end and backend Teams together into a single unit.
