You have web workers, generators, all the async stuff, futures and promises — plenty enough from the language perspective. Maybe node.js does not happen to be multi-threaded, but it's not about the language.
> By the same logic Python is multithreading-ready as well, since it's only a matter of it's major implementation why it doesn't support multithreading.
How web workers aren't threads? Browsers are more widely deployed than Node, even with the same V8 engine.
