node.js - Async call in node-webworker-threads? -

this hello world example node-webworker-threads page works fine, , generates worker said: hi ali:

var worker = require('webworker-threads').worker; var worker = new worker(function(){   postmessage("i'm working before postmessage('ali').");   this.onmessage = function(event) {     self.postmessage('hi ' + event.data);     self.close();   }; }); worker.onmessage = function(event) {   console.log("worker said : " + event.data); }; worker.postmessage('ali'); 

but not work, , can't figure out why. adding settimeout results in self.postmessage never getting called:

var worker = require('webworker-threads').worker; var worker = new worker(function(){   postmessage("i'm working before postmessage('ali').");   this.onmessage = function(event) {     settimeout(function() {         self.postmessage('hi ' + event.data);         self.close();     },0);   }; }); worker.onmessage = function(event) {   console.log("worker said : " + event.data); }; worker.postmessage('ali'); 

how async calls handled node-webworker-threads?

can explain webworker-thread example?

"workers don't have access settimeout, setinterval, etc. indeed, html timer spec not native v8 , need re-implemented in c++ level."
