Question

How does one use promises on Node.js running on Windows? For the life of me I can’t seem to get any example to work…

For example something like this doesn’t work:

var pinput = new Promise(
   function(fulfillPromise, breakPromise) {
     var btn = document.getElementById("button");
     var txt = document.getElementById("txt");
     btn.onclick = function() {
       fulfillPromise(txt.value);
     }
   }
);

pinput.whenOnly(function(value) { alert(value); });

Throwing in requires doesn’t help either:

Promise = require('promise');

All I get is either:

ReferenceError: promise is not defined

or

Error: Cannot find module 'Promise'

And I can’t seem to find the promise from the latest API either… (http://nodejs.org/docs/latest/api/)

Me be puzzled.

I believe promises were removed. See this Google Groups post for more information.
