Comparing a programming language(Python) and run-time environment(Node.js) is difficult in terms of their development capabilities. Most people may consider Python as a heavy language for backend and Machine Learning. On the other hand, Node.js is considered as the framework for server-side applications. We will compare them on the following parameters:

  • Development Speed
  • Product Scalability
  • Learning Curve
  • Libraries & Tools
  • Ease of Development
Let's have a look at these factors and the performance of Python and Node.js on these parameters.

Development Speed
Node.js is not suitable for multitasking and writing simultaneous code at once. This leads to a relatively slower speed of development and lower performance. The focus on other functionalities might lead to a lag that you didn't expect.

Python is fantastic for multitasking. It enables reusing the code for faster development. Python frameworks have built-in solutions to handle too many functions at once. There are less technical expectations that the Python developers need to meet.

Product Scalability
Node.js builds the asynchronous architecture in a single thread. The structure reduces the number of errors while developing web applications. It enables handling multiple requests at once and helps in building scalable applications.

Python does not support asynchronous architecture. However, it is extremely useful for building scalable, enterprise-grade applications. It may not be as scalable as Node.js. Python delivers robustness while building Machine Learning apps with heavy algorithms.
