workerNodes.call : Proxy

This exposes the api of a module that the worker nodes are working on. If the module is a function, you can call this directly. If the module exports multiple functions, you can call them as they were properties of this proxy.

Kind: instance property of WorkerNodes

nothing is mentioned about promises, and the example shows usage of promises
