Nodejs vs Python

Python is defined as a high-level, object-oriented programming language, however, NodeJS is an open-source framework that is used for creating both client-side as well as server-side apps. NodeJS is known for producing highly scalable as well as top-performance apps because of its robust ecosystem and broad tech stack. In this article, we will discuss the main difference between Node JS and python based on various factors such as their features, advantages, use cases, types, versions, and popularity.

What is Node JS?

JavaScript code can be run outside of a browser using the open-source, cross-platform runtime environment known as Node.js. The user must be aware of the fact that NodeJS actually is not a language developed for programming nor it is a framework. The majority of developers are perplexed and believe that it's a computer programming language or framework. For creating back-end applications like APIs for web apps or mobile apps, we frequently make use of Node.js.

Features of Node.js: As there are a lot of other languages used for programming, that also may be used to create back-end services, Node.JS's features make it very unique. They are
  • It offers quick and highly scalable services, 
  • It is simple to use for prototype and agile development.
  • Because JavaScript is used everywhere, creating back-end services with Node.js is simple for JavaScript programmers.
  • Consistent and clear source code.
  • large open-source library ecosystem.
  • Its nature is non-blocking as well as asynchronous.

What is Python?

A well-liked programming language is Python. In 1991, Guido van Rossum produced it, and it became available. We use Python for server-side web applications,  software development, mathematics, as well as system programs. Python is cross-platform compatible and works on MAC, Linux, Windows, etc. The syntax of Python is simple and resembles English. 

  • Python's syntax varies from various other computer languages in that it enables programmers to construct applications with fewer lines of code.
  • Python operates on an interpretation system, allowing for the immediate execution of written code. As a result, prototyping can proceed quickly.
  • Python can be used in a function, object-oriented, or iterative manner.

Python vs Node.js – Key Differences


Node JS operates on events. Its asynchronous input and output allow for a quick development cycle. As a result, it's the best choice for chatbots and online games. Python is a synchronous as well as a consequently slower language than Node JS and Node, respectively. Therefore, you should avoid choosing this language if the user project is similar to a chatbot. 


Python's first version was launched in 1991, but Node.JS was only just introduced in 2009.


According to GitHub, Python is the second most popular programming language, while Node.js is an open-source environment for JavaScript and not a programming language. Node.js is used to create frontend and backend applications using a single integrated stack, whereas Python is used to create difficult online projects such as big data, AI development, automation, and backend.

Speed and Performance:

When comparing Node.js with Python, JavaScript makes Node.js speedier while Python is extremely slow when compared to built languages.

Error Handling:

Node.js has high multithreading ability, hence it is well equipped for error handling. On the other hand, python enables very powerful troubleshooting.  


Node.js has an NMP package manager which involves huge documentation, creating a smooth learning curve for the language. Python on the other hand, has a PIP manager having a compact and clean mode. 


The asynchronous architecture of Node.js  for app development makes multithreading possible and makes the process of scaling simple. Hence, it is scalable. On the other hand, because of  Python's Global Interpreter Lock, it doesn't support multi-threading. Although scalability in python can be improved with imported libraries, it regrettably cannot compete with Node.js' inherent scalability.

Building Data and Memory Intensive Applications:

Python is primarily used for online and desktop applications, but Node.js is appropriate for cross-platform applications.


It comes up with new frameworks such as Jasmin,, Babel, etc. Python has multiple frameworks, hence showing an amazing extensibility such as Robot, Django, flask, etc. 


If you are familiar with JavaScript, you won't have any trouble with Node.js' syntax. However, unlike Node.js users, Python developers shouldn't have to write as much code. For those with technical expertise, in particular, reading and understanding Python code is simple.

Ease of Learning:

Because of its straightforward and simplified syntax, Python might be quicker to learn. Typically, Python requires fewer code lines to implement a given function than Node.js does to develop the same function.

Universal Usage:

Python is applied for complicated projects such as Artificial Intelligence development, automation, big data, and backend. However, Node. js is used to construct frontend as well as backend using a single integrated stack.

User Community:

A sizable and vibrant community exists for Node.js. It is an established open-sourced system with a significant user base. 10 years  after the launch, this technology has won the hearts of developers all across the world. You may locate Node.js developers with ease if you own a company. You can always count on peer help as a programmer.

In comparison to Node.js, Python is a bit older and also open-sourced. There are a huge number of participants from the user community, each with varying levels of skill. Again, if you're a developer or a business owner, you win from the vast community.

Features of Node.js


  • Our web application runs more quickly since the developers may use NodeJS to conduct non-blocking tasks.
  • The NodeJS framework is open-source and cost-free.
  • Developers can create a variety of servers using NodeJS, including HTTP, TCP, DNS, and others. NodeJS has a large number of built-in APIs.
  • Unit testing is supported in NodeJS under the name Jasmine for swiftly testing the ready code.
  • Applications create here, can be scaled both horizontally as well as vertically for enhancing performance.
  • In NodeJS, the usual ECMAScript could be utilized without any issues.
  • By selecting the NodeJS version, we are in command of determining the ECMAScript version to use, so the user doesn't need to depend on other users for updating their browsers.

Features of Python


  • It allows the Python interpreter to include low-level packages. Programmers can add or modify their tools using these modules.
  • It offers entry points to all significant business databases.
  • Along with OOP, it provides functional as well as structured program techniques.
  • It provides dynamic type checking and offers superior dynamic types of data.
  • It is simple to integrate with Java, C, COM, C++, ActiveX, and CORBA.

When to use Node.js

As a platform built on the JavaScript runtime of Chrome, Node.js aids in the development of scalable network applications. It is a great choice for creating data-intensive real-time applications since it uses an occurrence, non-blocking I/O strategy.

Node.js delivers improved results and quickness when compared to Python. Creating texting or talking applications is the best option. It is also helpful for creating e-commerce websites that rely on processing speed and heavy-load apps.

When to use Python

Open-source web frameworks, testing tools, and data analysis tools are all available in the Python library. As a result, it has one of the biggest programming environments. For beginner programmers, Python is the most approachable language thanks to the community's abundance of basic materials. In addition to being utilized for dealing with beginner-friendly devices like the Raspberry Pi, the program is also taught in institutions.

Python offers consistency, reliability, and ease of use as compared to Node.js. For creating scientific applications, large data applications, or social programs, it is strongly favored.
