• It’s easy to get started and can be used for prototyping and agile development
• It provides 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 cleaner and consistent.
• Large ecosystem for open source library.
• It has Asynchronous or Non-blocking nature.

Advantages

• Easy Scalability: Developers prefer to use Node.js because it is easily scaling the application in both horizontal and vertical directions. We can also add extra resources during the scalability of the 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, the event loop avoids HTTP overloaded 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 of JavaScript you can easily learn and build the application on NodeJS
• Advantage of Caching: It provides the caching of a 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 platforms for NodeJS application deployment which is easy to use without facing any issue.
• Corporate Support: Most of the well-known companies like Walmart, Paypal, Microsoft, 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.

Why NodeJS

JavaScript is one of the most popular programming languages in the world. It powers millions of websites today, and it has attracted droves of developers and designers to build features for the web. If you’re new to programming, JavaScript is easily one of the best programming languages to get under your belt.

Is Node.js Frontend Or Backend?

A common misconception among developers is that Node.js is a backend framework and is only used for building servers. This isn’t true: Node.js can be used both on the frontend and the backend.

One of the reasons Node.js frameworks are a popular choice for developers building a flexible and scalable backend is its event-driven, non-blocking nature. However, frontend developers will see these benefits of Node.js in their own work just as clearly.

Let’s take a look at why Node.js works for both backend and frontend:

Reusability – JavaScript is a common language that’s used to write both backend and frontend with the help of frameworks like Express.js and Meteor.js. Some popular stacks like MERN use Express.js as a backend (a Node.js framework). Multiple components can be reused between frontend and backend as well. Productivity and developer efficiency – Thanks to a reduction in context-switching between multiple languages, a great deal of developer time can be saved. Using JavaScript for both backend and frontend results in increased efficiency, as many tools are common for both. Huge community – A thriving online community factors into the speed of a successful development cycle. When you get stuck on a problem, there’s a good chance that someone’s already solved it and shared the solution on Stack Overflow. Node.js makes great use of this community, which is active and engaged when it comes to the popular runtime and its packages.

Platform architecture

Node.js brings event-driven programming to web servers, enabling development of fast web servers in JavaScript. Developers can create scalable servers without using threading, by using a simplified model of event-driven programming that uses callbacks to signal the completion of a task. Node.js connects the ease of a scripting language (JavaScript) with the power of Unix network programming.
