Frequently Asked Question 

What is Node.js?

Node.js is a compelling web development framework/platform that runs on the V8 JavaScript engine of Google Chrome and allows developers to build network applications easily and quickly by using push technology (instead of HTTP pull technology as seen in other platforms). It can be used for creating scalable real-time applications like chat, game servers, etc.

What is Python?

Python is a general-purpose, high-level programming language that can be used for web development and software/product development. The developers widely adopt it because of its clean syntax, easy-to-learn nature, and powerful libraries like Django (for web development), requests (for HTTP clients), etc.

What is the difference between Node.js and Python?

The following points highlight the significant differences between Node.js vs. Python:

1) Node.js is JavaScript-based while Python is not. The sole reason programmers are attracted to Node.js is that they can use the same language for backend development used in the front-end. While in the case of Python, developers need to learn a different language (for backend), this will be an advantage for some programmers because they can focus on learning just one programming language and do not need to switch the context from time to time.

2) Node.js uses a non-blocking I/O mechanism which scales very well and is better than Python.

3)  The node package manager (NPM), Backbone, Bower, and Grunt make Node.js an ideal technology for web development compared to Python. Also, the support for JavaScript code testing tools like JSHint makes it more robust and powerful.

4) Node.js has a vast developer community and is more popular than Python. The express framework makes Node.js web development easier than other platforms. Also, the support for features like web sockets makes it stand apart from alternative technologies like PHP, ASP, etc.

Which One is Better between Node.js vs. Python?

This question can be answered only after studying the requirements of a project. If a task requires a real-time application with instant responses, then Node.js will prove to be more beneficial because it can handle more requests in less time. In contrast, Python is not ideally suited for such problems (although there are ways like multi-threading, event, etc., to make it perform faster).

But if the task needs a project having less I/O operations and quick processing, then Python can be an ideal solution. Also, Python has the edge over Node.js when long-term stability is required or compatibility issues with other technologies used in the backend.

Python is much more stable than Node.js because it requires frequent updates in browsers to work with it. Also, Python is much easier to maintain when compared to JavaScript (to some extent).

Is Node.js Easier than Python?

No. Both are equally easy to learn, but node js is much more popular than Python in web development because of the following reasons:

  • Node.js framework is much easier to install and configure
  • The well-supported NPM makes the process of adding libraries/modules very simple
  • Popular tools like Grunt, Bower, and Gulp make it easier to work with node js.

Is Python better than Node.js?

Yes, Python is much better for long term projects because of the following reasons:

  • Stability and compatibility with other technologies are two major advantages of Python. 
  • Also, there is tremendous community support which makes it more reliable.
  • Python has an extensive standard library which makes it ideal for performing complex operations without writing much code. The presence of robust data structures gives it an edge over other technologies.

Which is Faster, Node.js or Python?
