node js vs python which backend technology better to utilize

Quick Summary : When it comes to backend development, Node.js and Python offer distinctive advantages. Node.js excels in real-time applications and scalability, while Python boasts versatility with its vast library ecosystem. Understanding your project requirements and considering performance, community support, and development expertise will aid in selecting the ideal backend technology.

The majority of the developers use backend technology for their web assignments based on the knowledge they have, and they are familiar with the tech. While this is easy, it is frequently not the best way for organizations to achieve their goals.

Furthermore, selecting the right backend technology for the web development project is very important for every developer. It determines the project’s performance, resource consumption, deployment simplicity, scalability, and, in some instances, its success.

Python vs Node JS are extensively used server-side technologies, even though both are introduced in different time frames with different usabilities.

Python was first introduced in 1991 and is still used today. This programming language was designed to create mobile and online applications on the server-side.

In contrast, Node JS came in 2009 as a JavaScript runtime platform that revolutionized JS on the server. If you are the CTO or owner of the app, you may find it difficult to choose between Node JS vs Python.

To make the best possible decision, find out and analyze their strengths and weaknesses, and use them to your advantage when running a web app development company!

What is Node JS?

Node JS is an open-source, cross-platform, server-side JavaScript runtime environment (Framework) that runs JavaScript code outside a web browser. These works on Chrome’s V8 JS platform, and Ryan Dahl built it in 2009. The tool enables developers to create command-line tools and network applications to generate dynamic content for web pages before sending them to users’ browsers.

It enables programmers to design real-time web applications that run on distributed systems such as the Internet (Linux, Microsoft Windows, Os x). JavaScript is used to create its applications. Nodejs programming language also comes with a handy JavaScript-rich library, which makes web-based development a breeze.

Pros of Node JS

A strong technological foundation

It helps developers to create the project using the MEAN stack Technology that consists of MongoDB, Express.js, Angular, and Node JS, which cater to all your requirements.

Event-driven model

Node JS is 2-3 times quicker than Java, PHP, and Go, according to Toptal’s examination of server tool speed and efficiency. No matter what the user does, Node JS machine learning executes an algorithm based on event-based programming.

Microservices require flexibility to develop

Programmers can update multiple modules simultaneously via a package manager that offers free modules that can use to create microservices.

Diverse Ecosystem

The Node JS package manager offers a selection of open-source JS plugins with a rich ecosystem.

Cons of Node JS

Problems with performance

Node JS is a programming language based on JavaScript that performs tasks with minimal CPU usage. CPU-bound jobs emerge more frequently when you utilize Node JS for the backend runtime environment.

Quality control

Because Node JS is open-source, its updates aren’t subjected to rigorous quality control, favoring quantity over quality.

Callback problem

In Node JS, tasks are tracked using callbacks. As the project grows and more processes are active, the number of callbacks also increases. Callbacks can cause developers to become lost and miss critical defects.

What is Python?

It is a totally object-oriented programming language that involves high complexity levels. The software has many libraries, APIs, and extra features due to its existence for more than 30 years. Python is flexible to a wide range of programming models and is widely used within big corporations.

It has a vast developers community, libraries, and platforms for supporting it. As a result, it is used by almost every enterprise that builds applications for a variety of purposes, often with diverse usage.

Advantage of Python

Even though Python is not primarily designed for web programming, it does provide some advantages.


The Python syntax is quite conversational, which makes it easy to understand code files. Simple chores take 10-30 minutes to master.

Machine learning and AI development opportunities

The Python language comes with a number of AI libraries pre-installed (Tensorflow, Pylearn2, and Scikit-learn for data analysis).

Multiple hosting

Many hosting services accept Python natively and enable the integration of APIs and other plugins. AWS, TMDHosting, A2 Hosting, Heroku, and various different options are also available.

Disadvantages of Python Language

The universality of Python makes it less efficient for web development.

Work at low speeds

The comparison of JavaScript vs. Python performance shows that it is much slower on the server-side operations. The language contains multiple concepts at different levels to make it easier to understand.

The issue with mobile development

It’s not a native language for either Android or iOS ecosystem, and it’s not recommended for cross-platform development. You can use frameworks and platforms to adapt the language to mobile development, but performance will be poor.
