I’ve been exploring backend frameworks lately, and I’m trying to decide between FastAPI (Python) and Node.js with Express.
I know both are powerful and widely used, but I’d like to know which one is better suited for modern API development, especially when it comes to performance.
Has anyone worked with both and can share insights about which one to pick for a new project?

Choose FastAPI if:

• You prefer Python or work in ML / data-heavy environments.
• You want clean, typed APIs with automatic docs.

Choose Node.js + Express if:

• You need maximum concurrency and a huge plugin ecosystem.
• You’re building in a JS-based stack (frontend + backend). (Mark this Up,if helpful 😁)
