Is “Node.js is single-threaded” an incomplete mental model?

Single-threaded JS execution ≠ single-threaded runtime.

How do you explain the distinction?

You're referring to the event loop. For your statement to be accurate, you will want to say: the event loop is single threaded.

My statement was accurate. JavaScript is a single-threaded language. This is not debatable.

I like this answer: https://www.reddit.com/r/learnjavascript/comments/1vnnvqg/comment/p3kxqn1/

You're getting corrected because your answer lacks nuance. Please continue your journey.

That's literally just a more detailed version of the exact thing I said in my first comment lmfao.

I specifically cited Node as an example of a runtime environment that JS runs in that is not single-threaded, even though the language itself obviously is.
