Node.js vs Python: A Comparison

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.

  1. 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.
  2. Product Scalability
