Io.js v3.0.0
I'm hoping they will converge towards Go, with its fine-grained threading model (with shared state), as opposed to an asynchronous model which is effectively the cooperative-multitasking that we remember from Windows 3.1.<p>Asynchronous programming forgets that the CPU is also a resource that needs to be managed in a non-blocking way. Currently, in Nodejs, long-running computations (e.g., computing a large prime number), totally block the CPU.<p>EDIT: For anybody saying that shared-state is a bad thing, read up on functional datastructures with structural sharing.
