What is Node.js?

Node.js is a runtime environment based on JavaScript, a widely-used programming language. Node.js’s primary application is to help developers in building quick and scalable network applications. It uses a non-blocking, event-driven I/O model, allowing it to remain efficient and lightweight. 

Due to those qualities, Node.js is suitable to build real-time applications that require a lot of data and can run across various distributed machines. It is an open-source runtime environment to develop networking applications. It is cross-platform too, which lets developers use it on different platforms.

You can write Node.js-based applications in JS (JavaScript) and run them on Microsoft Windows, OS X, and Linux through the Node.js runtime. Another reason for its vast popularity is its extensive library for JavaScript modules. They help you develop web applications through Node.js much quickly and easily.

Features of Node.js

The following are some qualities of Node.js that make it the preferred choice of many developers and software architects:

1. Event-driven and Asynchronous

The APIs of Node.js’s library are non-blocking (asynchronous). This means a Node.js-based server doesn’t have to wait for an API to return any data. The server would call an API and move to the next one. A Node.js event notification would help the server in getting a response from its last API call.

2. Highly Scalable

Even though Node.js employs a single-threaded model, its event mechanism helps its server respond in a non-blocking manner. This quality makes Node.js servers very scalable. Traditional servers have limited threats to handle their requests, while Node.js servers don’t face this issue. The single-threaded Node.js program can provide service to a much larger quantity of requests in comparison to any traditional server.


Node.js is built on Google Chrome’s V8 JS Engine. Google’s infrastructure makes Node.js very powerful and fast. You can execute its library code quite quickly, which allows you to enhance your entire project’s efficiency. By using Node.js, developers can reuse code for common operations and, thus, save a lot of time in writing code.

3. Open-source

Node.js is an open-source solution. This means you can use it for free. This quality has helped Node.js is becoming much popular among developers and programmers, too, as it has made it quite accessible. 

Its library, Node.js Package Manager (npm), is among the largest libraries of modules and tools. So by using Node.js in your project, you can reduce the overall operational costs of your project substantially. 

npm allows you to install and manage dependencies, download frameworks, set configuration variables, and get the necessary development utilities.

4. Doesn’t Buffer

All applications based on Node.js don’t buffer data. They produce data in chunks. 

5. A Vibrant Community

Node.js has many achievements under its belt. It has more than 60,000 stars on Github, 7,500+ votes on StackShare, and more than a billion downloads. Node.js has a large community of its users, continually updating its frameworks, modules, and tools as it’s widely popular. The community is quite helpful, and learning it will help you become a part of the same. 

6. Efficient

You can use Node.js for the front-end and the back-end sections of your project. Using one language for both sections can reduce the development time significantly and become more efficient. It allows you to reuse the code for simple operations across your project’s ecosystem. This is a prominent reason why it’s so popular among development teams and why you should take a Node.js online course free.

Web design is more concerned with the website's front-end, whereas web development is more concerned with the back-end.

3. Why do people use Python more than Ruby?

Python is a programming language with a number of properties that can lead to efficient code, including easy syntax and sophisticated data structures. It's a high-level language, which means the programmer doesn't have to worry about the machine's inner workings. Python is a free and open-source programming language licensed under the GNU General Public License. Ruby is a programming language that emphasizes efficiency and simplicity. It includes a robust standard library and an elegant syntax that is easy to read. Ruby is a dynamically typed language, which means variables don't have a fixed data type and can change throughout the execution of a program. Ruby is also an object-oriented language, which means that everything in it, even numbers and strings, is an object. Python is more popular than Ruby because it is more beginner-friendly. It has a larger community and more resources available online.
