Curious to know why does node.js need Python ? Does it use Python underneath its API

Answer 1

Node.js is built with GYP — cross-platform built tool written in Python. Also some other build steps are implemented in Python. So Python is required for building node from source.

But you also need Python for building native addons.

Answer 2

Yes, node uses some python scripts under the hood, though Node is largely written in C++.

See some of Node's python code here:

E.g., js2c.py converts Javascript into C-style char arrays:

In general, if a package tells you that it requires Python, then it is almost certainly using Python ;)
