C'mon, the book is called Javascript: The Good Parts (cough, 2008 vintage) This post is just chock full of bizarre straw-men in the guise of actual argument: Systems stopped using cooperative multitasking at least 20 years ago because it sucked compared to the alternative of automatic, preemptive multitasking. And yet Node.js harks back to those dark days with its callback-based concurrency, all running in a single thread. What the heck? No comprehension of evented systems? Reactive programming, anyone? No acknowledgement of the use cases when these systems do (or do not), in fact, kick total ass? Yes, the vanilla JS nested callback thing is a bit annoying. So don't do it. Use some of those FP chops and unwind it. Maybe a fold or a monad or some categorical pocket lint. Just please let cooperative multitasking have a nice rest.
