Python vs NodeJS - Which one is the Best Framework

Summary: NodeJS and Python are the most compared backend frameworks for web application development. Since both frameworks have the same popularity, it becomes difficult for users to choose the best between Python vs NodeJS. This blog study features the pros, cons, and similarities between NodeJS and Python. Read the blog to choose the effective framework between Python vs NodeJS.

While creating web apps, Python vs NodeJs are the most used platforms. The application’s server-side and backend side is the project’s support system; the entire client-side will run on it. However attractive your front end is, the application will only be successful if you deliver a robust backend.

This leads to a selection between the two, i.e. NodeJS vs Python

It is essential to understand that Node is not a programming language but a JavaScript runtime environment. In contrast, Python has been a dependable programming language with established features for 30 years.

In recent years, the popularity of Python and Node.Js has increased quickly. As per Stack Overflow, Python is the most commonly used programming language, whereas Node.JS is the top choice for server development. This article will compare Node.js and Python, explore their applications in various industries, and highlight their vital technical characteristics.

To make the selection easier, here in this blog, we have mentioned the comparison of Python vs NodeJS.

Introduction to NodeJs and Python

One important difference between Node.js and Python is that Node.js is a runtime environment that depends more on JavaScript. It is used to develop apps that need frequent communication with web servers and is designed to use computing resources effectively.

What is Node.JS?

What is Node.JS?

Node.Js is defined as a server-side platform developed on the JavaScript Engine of Google Chrome. It utilizes a non-blocking, event-driven I/O model. Also, it enables developers to develop a data-intensive, real-time app that can be executed on various devices. Its scripts are written in JavaScript. Executing on Operating system X, Linux operating system, and Microsoft Windows is possible. Majorly, Node.JS is used to run real-time server apps.

What are the Features of Node.JS?

  • The Node.JS framework allows a single-threaded model that uses event looping and allows the server to respond in a non-blocking pattern.
  • The foundation of the V8 JavaScript Engine ensures its execution of code smoothly and efficiently.
  • Node.JS does not change data output because applications deliver data in small pieces.

What is Python?

What is Python?

Python is a universal programming language that users can utilize to develop big data, automation, backend development, etc. Its syntax, dynamic typing, and interpreted nature make it an ideal language for scripting. Python supports various programming patterns, including object-oriented, functional, and procedural styles. Additionally, it is an interpreted language, meaning it can be converted to computer-readable code during execution time.

What are the Features of Python?

  • Python interpreters can include low-level modules which enable programmers to customize their tools.
  • It also provides interfaces to major commercial databases. It supports functional, structured, and object-oriented programming (OOP) methods.
  • Python offers high-level dynamic data types and supports dynamic type checking.
  • It seamlessly integrates with C, C++, C.O.M., ActiveX, CORBA, and Java.

Pros and Cons of Node.JS and Python

After briefing Node.JS and Python, let us learn the pros and cons of Node.JS vs Python.

Advantages of Node.JS

  • For developing the microservice architecture, it is necessary to have multiple executions of components and development.
  • NodeJS can provide free components allowing developers to work on several modules simultaneously.
  • Using Node.JS app development can be utilized with the MEAN technical stack, which has the best database support for front-end and back-end.
  • Because of high compatibility, Node.JS saves overall development costs and speeds up development.

Cons of Node.JS

  • The main drawback of Node.JS is the repetitive API switch that develops backend incompatibility.
  • There is also an issue of nested callback functions, which, as a result, decreases the code quality and creates difficulties in maintaining and solving.
  • NodeJs cannot execute multiple tasks because it works on a single thread.
  • On receiving the request, the system will complete the process of requesting and then will accept the other requests.

Pros of Python

  • Python delivers more readability and fast code interpretation, making the development process faster.
  • Python will require less code which will result in less development time.
  • Python is more compatible and flexible with other programming languages and platforms. Hence, it becomes easier for
  • developers to integrate Python with other programming tools and languages.
  • With huge library support, Python can develop any application, e.g. Game apps development, web app development, etc.

Cons of Python

  • Python does not support mobile app development; hence, it is not a compatible language for native application development.
  • iOS and Android both do not support Python for mobile application development.
  • Unlike NodeJS vs Python speed, Python has a slower execution time than any other programming language.
  • Python has higher memory consumption issues which result in bad-quality app development.

Comparison of NodeJS vs Python

NodeJS is faster than Python and hence it is used to develop both client-side and server-side network applications. NodeJS is also capable of handling high memory whereas Python is not a capable for applications requiring high memory. But still Python is utmost choice for developing back-end applications. Check out the difference between NodeJs and Python.

NodeJS Python
Highly secured and prevents data breaching Slow in process because of single flow of code. 
Possess powerful runtime for asynchronous request Possess good support for asynchronous request.
Decreased in readability due to Callback Delivers high readability in code
JavaScript Interpreter PyPy Interpreter
Best for memory-intensive process Fits best for large projects
Preferred for real-time applications Not preferred for real-time applications
Compatible for front-end development and back-end development Compatible for developing an application having less code. 
LinkedIn, PayPal and Netflix are application examples of NodeJs development Reddit, Facebook and Google are application examples of Python development. 
It is contemporary and open-source with larger community  It is older with a larger community.

Which are the Most Popular Use Cases of NodeJS and Python?

Python and NodeJS both have particular use cases. The most popular web technology is NodeJS, whereas Python is the fourth most popular development technology, according to the data.

So, after going through the pros and cons of Python vs NodeJs, we have now mentioned the list of use cases and the most popular apps built using NodeJS and Python.
