Nodejs Vs Python: An All-Inclusive Comparison

 An All-Inclusive Comparison

Before we start comparing Python vs Nodejs, let’s understand that Python is a programming language while Nodejs is a runtime environment for JS

Now, let’s compare two prominent contenders in the world of backend development, to help you decipher their strengths, weaknesses, and decide the one that aligns better with your project goals.

I. Nodejs vs Python:Speed and Performance

When choosing a backend technology, speed & performance are the most important aspects that we look for. Your application has to load fast so your customers don’t abandon your site in the first place and then every web element and process should work perfectly.

Thus, let’s first compare Python vs Node Js performance!

  • The non-blocking, event-driven architecture of Nodejs makes it lightning-fast.
  • It can process concurrent user requests at a time, thanks to the single-threaded event loop.
  • In Nodejs development, you can code outside web browsers with the help of TCP sockets.
  • Node is built on the fastest v8 Javascript engine, making its application performance remarkable.
  • Caching in Node helps with high speed.
  • Python’s single flow of code causes slower processing of requests.
  • Unlike Nodejs, Python doesn’t utilize caching and can’t perform a quick recall of data from the server.

Winner: Nodejs

II. Nodejs vs Python: Scalability

When you develop an application, making it scalable is quite essential as you need to accommodate the growing needs of your customers.

  • The asynchronous architecture supports multithreading and makes it highly scalable.
  • Unlike Python, Nodejs applications use microservices and modules. Thus, scaling it would mean adding more modules without affecting the entire app
  • Node lets you scale vertically and horizontally.
  • The use of global interpreter lock in Python doesn’t support multi-threading. Therefore, scalability can be a concern here. Even so, you can scale Python-based applications using imported libraries, but it won’t compare to the scalability of Nodejs apps.
  • It becomes very difficult and complex to maintain a growing Python application.

Winner: Nodejs

III. Nodejs vs Python: Extensibility

While working with a backend platform, you should be able to add more features and functionalities to the base platform. It ensures you can build a website or app as per your unique requirements.
