How do Python and Node.js compare in terms of performance?

Python and Node.js have different performance characteristics. Node.js is generally faster for I/O-bound tasks due to its non-blocking architecture, while Python excels in CPU-bound tasks but can be slower in handling concurrent requests.

What factors affect the performance of each?

Factors include the nature of the task (I/O vs CPU-bound), the efficiency of libraries used, and how well the code is optimized. Node.js benefits from its event-driven model, while Python's performance can be impacted by its Global Interpreter Lock (GIL).

Which one should I choose for a web application?

It depends on your application's requirements. If you need real-time features and high concurrency, Node.js is a great choice. For data analysis or machine learning applications, Python might be more suitable.

Can you give examples of applications built with each?

Sure! Node.js is often used for chat applications and real-time collaboration tools, while Python is popular for data science applications and web frameworks like Django.
