This is how it works in dotnet.

var val = await Task.Run(() => doSomeThreadedWork(param));

Indicates to the runtime that the specified delegate may be run on another thread. This doesn't explicitly start a new thread but rather just allows the delegate to execute on one of the thread pool threads that is managed by the runtime. It uses heuristics to decide how many threadpool threads to maintain and whether to actually use one of them to execute your delegate. A similar model would be very useful to have in JavaScript.

The issue is that in .Net there are locking primatives to access shared values... where as in Node/JS you would need something that only allowed passing of strings, other primatives, and SharedArrayBuffer or similar objects that don't change underneath unexpectedly.
