Developing Solutions In NodeJS Vs Python: Pros And Cons

NodeJS and Python are two essential solutions for back-end developments. These both are the programming languages (although, Node is a runtime environment for JavaScript) and established for server-side application development. NodeJS is based on JavaScript and runs on V8engine while python is object-oriented and high-level language.  

NodeJS offers great performance and a platform for developing messaging or chatting applications, while Python supports functional and structured programming methods. If you are intelligent and understandable then it is not a big task to get what type of application you want to develop. However, no language is bad but it all depends on you and the unique variable associated with the project, which language you need to choose according to your project.   

Every language has its own specifications and demands. And when you build an application, it is most imperative to choose the right technology for your project. We strive to make you more clear about both languages with the help of below pros and cons. 

Pros of NodeJS :

1.    Fats server solution 

2.    Scalable solution 

3.    Single language for front-end and back-end. 

4.    Easy to support 

Cons of NodeJS:

1.    Bad quality or lack of documentation for some modules in npm 

2.    Less effective with CPU-intensive operations 

3.    Error in handling 

Pros of Python:

1.    Easy to use 

2.    Readily approachable to PHP code 

3.    Rich standard library and ecosystem 

4.    Fast development 

Cons of python:

1.    Unsuitable for memory intensive process 

2.    Poor in newly included functionality 

3.    Lack of support for DSLs (Domain-Specific Languages) 

What is Node.js?

Node.js is a server-side platform built on Google Chrome's JavaScript Engine. It uses a non-blocking, event-driven I/O model. It allows developers to create data-intensive real-time applications that run across distributed devices. Its applications are written in JavaScript. It can be run on OS X, Microsoft Windows, and Linux operating systems. It is widely used to run real-time server applications.

What is Python?

Python is an object-oriented, high level, dynamic and multipurpose programming language. Python's syntax and dynamic typing with interpreted nature, make it an ideal language for scripting.

It supports multiple programming patterns, including object-oriented programming, functional programming, or procedural styles. Moreover, it an interpreted language which means it cannot convert to computer-readable code before its runs at runtime.

Node.JS Vs. Python

Node.js is best suited for asynchronous programmingPython is not exactly the best option for asynchronous programming.
Node.js is pure JavaScript, so its basics remain simple for the developers to learn.The biggest advantage of using Python is that developers need to write fewer lines of code.
Node.js lacks the clean coding standards. That's why it cannot be recommended for larger projects.It is ideal for a large project as it can do anything that can be done using PHP code.
Node.js is an ideal platform available right now to deal with real-time web applications.Not an ideal platform to deal with real-time web applications.
It best suited for small projects to enable functionality which needs less amount of scripting.Python is suited for developing larger projects.
Best for memory intensive activities.Not advisable for memory intensive activities.
Node.js is a better choice if your focus is on web applications and website development.Python is an ideal platform to do multiple things - web applications, integration with back-end applications, numerical computations, machine learning, and network programming.
Node.js utilizes JavaScript interpreter.Python using PyPy as Interpreter.
Node.js supports callback. Its programming is based on event/callback that makes it process Faster.It supports generators which makes it much simpler.

Selecting a development platform is significant steps in the app development phase. Node.JS and Python are certainly two highly discussed languages nowadays. Let where we can use Node JS and when to use python.

When to use Node js?

As Node.js is a platform built on Chrome's JavaScript runtime it helps to develop building scalable network applications. It uses an event-driven, non-blocking I/O model which makes it an ideal option for developing for data-intensive real-time applications.

Node.js offers greater performance and speed. It is an ideal solution for developing messaging or chatting applications. It is also useful for developing heavy-load applications and e-commerce sites that depend on the speed of processing.

Apps best suited with Node JS:

When to use Python?

Python has a library of open source data analysis tools, web frameworks, and testing instruments. Therefore, its ecosystem one of the largest out of any programming community.

Python is a most accessible language for new programmers as community provides many introductory resources. The language is also taught in universities and used for working with beginner-friendly devices such as the Raspberry Pi.

Python is also featuring consistency, stability, and easiness of use. It is highly preferred for developing scientific applications, big data solutions, and government projects.

Apps best suited with Python


Node.js is a server-side platform. It is built on Google Chrome's JavaScript Engine. It offers features like single thread, very fast performance and no buffering.

Python is an object-oriented, high level, dynamic and multipurpose programming language. It has features like support for major databases, functional and statured programming, etc.

Node.js can be used for client and server web development.
