Node.js is an open-source, cross-platform JavaScript runtime environment used for executing JavaScript code outside of a web browser.

Node.js is a great web framework for beginners because it works great for data-intensive applications, like streaming and real-time apps, and Node.js makes it easy to start building the back-end.

Node.js allows us to use JavaScript everywhere and on any browser, including MacOS, Linux, and Windows. When we say everywhere, we mean the front-end, the middle-ware, and the back-end. Node.js is, therefore, part of some very popular web development stacks, such as the MERN stack, MEVN stack, and MEAN stack.


Node.js offers an Easy Scalability

One of the key advantages of Node.js is that developers find it easy to scale the applications in horizontal as well as the vertical directions. The applications can be scaled in horizontal manner by the addition of additional nodes to the existing system.
Moreover, Node.js also offers you the option of adding extra resources to the single nodes during the vertical scaling of the application. So, it is highly scalable and provides better option than other JavaScript servers.

Easy to Learn

Since JavaScript is one of the most popular programming languages, most of the front-end developers have a good grasp over it.
It becomes much easier for them to start using the Node.js at the backend. It is easier to learn Node.js and consumes less time to work with it.

Node.js is used as a Single Programming Language

Node.js offers the developers the luxury of writing the server-side applications in the JavaScript. This allows the Node.js developers to write both the front-end as well as the back-end web application in JavaScript using a runtime environment.
And they don’t need to use any other server-side programming language. It also makes the deployment of the web applications simpler because almost all the web browsers support JavaScript

The Benefit of Fullstack JS

Node.js has been regarded as a full-stack JavaScript for serving both the client and the server-side applications.
Therefore, the advantage is that you don’t have to hire separate developers for backend as well as the front-end development. It saves both your valuable money and time

Known for Offering High Performance

It has been mentioned earlier that Node.js interprets the JavaScript code via Google’s V8 JavaScript engine. This engine complies the JavaScript code directly into the machine code. This makes it easier and faster to implement the code in a effective manner.
The speed of the code execution also enhanced by runtime environment as it supports the non-blocking I/O operations

The Support of Large and Active Community

Node.js is blessed to have a large and active community of developers who keep on continuously contributing towards its further development and improvement.
In fact, the groups of developers are well supported by the JavaScript programmers providing ready-made and easy solutions and codes in GitHub. It is expected that the developers will initiate many further developers in the future.

The Advantage of Caching

The open-source runtime environment of the Node.js also provides the facility of caching single modules. Whenever there is any request for the first module, it gets cached in the application memory.
The developers don’t have to re-execute the codes as caching allows applications to load the web pages faster and responds more swiftly to the user.

Offers the Freedom to Develop Apps

Another advantage that Node.js offers to the developers is the freedom to develop the apps and software.
This is one essential feature, which remains absent in Ruby on Rails imposing certain guidelines. You can begin everything from the scratch while developing applications

Getting Support for Commonly Used Tools

With Node.js, the developers can get an extended support for the various commonly used tools. Let’s take an example. Suppose, you want to test the source code of Node.js application; you can do so by using the Jasmin and other such unit-testing tools.

Handles the Requests Simultaneously

Since the Node.js is providing the option of non-blocking I/O systems, it relatively helps you to process several requests concurrently.
The system can handle the concurrent request handling efficiently better than others including Ruby or Python. The incoming requests get lined up and are executed quickly and systematically.

Node.js is Highly Extensible

The Node.js is known to be highly extensible, which means that you can customize and further extend Node.js as per their requirements.
You can also make use of JSON to provide the scope for exchange of data between the web server and the client. It also is facilitated with built-in APIs for developing HTTP, TCP, and DNS etc. servers.
