Welcome to EZtek’s Blog!
Today we are talking about Python and NodeJS. Read this article to learn their pros, cons and which of them you should choose for your project. On our channel, we share thoughts on recent developments in the tech industry, follow us not to miss new Blogs.

How to choose between NodeJS and Python?

How to choose between NodeJS and Python?
Well, when we choose the tech stack for our clients, we at EZtek usually focus on the criteria as:

  • What kind of project are we dealing with?
  • What kind of product do we expect to deliver?
  • What is the project’s reach?
  • What resources do we currently have?
  • What is the situation on the market?
  • What are our main performance criteria?


It is an object-oriented, dynamic language known for its simple, organized syntax and universality. Python is the most popular programming language in 2020 and it’s used by 30% of developers.


Fast Development and Deployment

Which allows developers to write complicated code quickly.

Simple Syntax

That provides describing complex concepts in a few code lines.

Large Ecosystem

It is the result of Python’s ability to respond to multiple development challenges. Among the most popular packages in a Python ecosystem, we name:

  • Machine learning and deep learning resources: which includes libraries like Scikit-learn, Torch and Tensorflow.
  • Language processing: which has NLTK and Gensim
  • Web development: which includes frameworks like Django and Flask.

Large Community

It might seem like an insignificant advantage at first but we actually found that having a strong community makes professional growth and experience exchange easier.


Lower performance speed

Python is great at handling intensive operations but they take more time to process. If you need to run multiple concurrent requests, NodeJS is a better option.

Low performance quality in mobile versions

Here, the low speed performance question is even more of a problem than on desktop and another problem with adapting Python code to mobile is that it doesn’t mix well with native components.


Actually, it is a runtime environment that’s based on a Javascript language. NodeJS is the most popular development framework worldwide and about 53% of all developers use it for their projects.


Fast performance

It is the result of the non-blocking input and output.

Full-stack development

Many enterprises switch to NodeJS to use Javascript both on the Front-end and the Back-end. It provides:

  • Better mutual understanding in the development team.
  • Saving time and resources by reusing code
  • Access to a large talent pool.

Great for Microservice Development

Well, its ecosystem has many NPM packages that make it easier to modularize their architecture and migrate from monoliths. Here, we would like to recommend our blog post on the best NodeJS frameworks.


Poor at processing large data volumes

  • Because it uses a single thread event loop to process requests. If it’s a computation, NodeJS will take a while to get the result, the thread will be blocked and other operations won’t go through.
  • The other reason is a NodeJS vs Javascript problem. Javascript is essentially a front-end language that contributes to NodeJS, low CPU handling capacities, it doesn’t communicate as smoothly with the hardware and processing units.

Messy Syntax

NodeJS has multiple inconsistent models, often lacks semantic standardization and is subject to frequent changes.

Use cases of Python and NodeJS

Once we look at top websites, NodeJS becomes a leader because it fits well with the needs of large companies.


  • Data science
  • Web development of complex platforms
  • 2D and 3D GUI
  • Scientific software
  • Scrapers and parsing software
  • Testing and development.


  • Streaming applications
  • Collaboration platforms
  • Single-page applications
  • Real-time messengers
  • Enterprise applications.

Both NodeJS and Python offer excellent possibilities to development teams. So, the final choice depends on the characteristics of your project.
