Should you choose Node.js or Python for backend development in 2025—and why?

Compares Node.js and Python for backend use cases, focusing on performance, concurrency, scalability, and typical project suitability.

According to industry analysis: • Node.js excels due to its non-blocking, event-driven architecture and V8 engine—ideal for high-performance, real-time use cases like chat apps, streaming, and concurrent APIs. • Python, despite being slower due to its GIL and synchronous model, shines in AI/ML pipelines, data processing, and rapid coding with its readability and rich ecosystem.
