Node.js came into the process when the original JavaScript developers extended it from something that could only be done in the browser to something that could be run on your computer as a standalone application. Now you can do much more with JavaScript than create interactive websites.

JavaScript now has the ability to do things that other scripting languages ​​like Python can do. Both your JavaScript browser and Node.js run on the V8 JavaScript runtime engine. This engine takes your JavaScript code and converts it to faster machine code. Machine code is a low-level code that the computer can execute without having to first interpret it. 

Well, the simplest definition of Node.js is that it is a run-time Javascript environment that helps running server-side JavaScript. It is an open source cross-platform JavaScript that helps in developing real-time network applications. Offers event-driven and asynchronous API I / O developers. It can also interpret JavaScript code using the Google V8 JavaScript engine. 

As you know, Node JS is an open source environment of which you can include in open source eCommerce Platforms. 

At the moment, JavaScript is much more popular than other client-side programming languages. As a cross-platform runtime environment, Node.js allows developers to execute JavaScript on web servers. Whereas Node.js is a bit different from other JavaScript frameworks that are commonly used. Interpret JavaScript code using the Google V8 JavaScript engine. 

Furthermore, most of the basic modules of the open source runtime environment are written in JavaScript. Web developers can then use Node.js to use JavaScript for web application frontend and backend development. There are many useful Node JS frameworks that help web and mobile app development easier and faster. However, it is also important for Web developers to understand the main advantages and disadvantages of Node.js. 

In addition, it operates on a loop based on single-threaded events to make all non-blocking executions. However, Node.js cannot be considered a framework and has nothing to do with PHP, .NET or JAVA.  

Check out the advantages and disadvantages of Node JS. 

1. Node.js offers easy scalability

One of the main advantages of Node.js is that developers find it easy to scale applications both horizontally and vertically. Applications can be resized horizontally by adding additional nodes to the existing system. In addition, Node.js also offers the possibility of adding additional resources to individual nodes during the vertical resizing of the application. Therefore, it is highly scalable and offers a better option than other JavaScript servers.

2. Easy to learn 

Because JavaScript is one of the most popular programming languages, most front-end developers have a good understanding of it. It becomes much easier for them to start using Node.js in the back end. It is easier to learn Node.js and consume less time to work on it.

3. Node.js is using as a single programming languages 

Node.js offers developers the luxury of writing server-side applications in JavaScript. This allows Node.js developers to write both the front-end and back-end Web application in JavaScript using a runtime environment.

And they do not need to use any other server-side programming language. It also simplifies the deployment of Web applications since almost all Web browsers support JavaScript. 

4. The advantage of Fullstack JS

Node.js was considered as full JavaScript to serve both the client and the server-side applications. Therefore, the advantage is that it is not necessary to hire separate developers for backend and front-end development. Save both precious time and money.

5. Known to offer high performance 

It has been mentioned previously that Node.js interprets JavaScript code via the Google V8 JavaScript engine. This engine complies with JavaScript code directly in the machine code. This makes it easier and faster to implement the code effectively.

The speed of code execution is also improved by the runtime environment as it supports non-blocking I / O operations. 

6. The support of the large and active community 

Node.js is fortunate to have a large and active community of developers who continue to contribute continuously to its further development and improvement.

In fact, developer groups are well supported by JavaScript programmers who provide ready-made solutions and codes in GitHub. It is expected that developers will launch many other developers in the future. 

7. The advantage of caching 

The open-source Node.js runtime environment also offers the possibility to cache individual modules. Whenever there is a request for the first module, it is cached in the application.

Developers do not have to re-run the codes because caching allows applications to load web pages faster and respond faster to the user. 

8. Offers the freedom to develop apps 

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

9. Node.js is highly extensible 

The Node.js is known to be highly extensible, which means that you can further customize and extend Node.js according to their requirements. You can also use JSON to provide space for data exchange between the Web server and the client. It is also facilitated with integrated APIs for the development of HTTP, TCP and DNS servers, etc.

10. Get support for commonly used tools 

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

Likewise, if you want to identify and install project dependencies, you can use npm, a powerful package manager. You can use grunt to perform project activity. 

11. Manage requests at the same time

Since Node.js provides the option of non-blocking I / O systems, it is relatively easy to process multiple requests at the same time.

The system can handle the simultaneous handling of requests efficiently better than others, including Ruby on Rails web development or Python. Incoming requests are aligned and executed quickly and systematically.
