Yeah but node.js predates asyncio by about 5 years. Python was early to the game with asyncore and Twisted (circa early 2000's), but the async I/O support stagnated and left a big hole for node.js.
Part of the reason for stagnation was because you really need new language features -- i.e. yield/send, yield from, etc. JavaScript already had the necessary language features for its concurrency model.
That's a good point. I also think `asyncio` was way too late in the game. I just wanted to mention the feature that was missed from your comment, which I think is not fair to Python.
