Qsequence, a simple sequencer for Q

Qsequence.js

"use strict";

var Q = require("q");

// Worker function
function logAndIncrement(val) {
  console.log(val);
  return val + 1;
}

// Normal
Q(0)
  .then(function(v) {
    return Q(logAndIncrement(v));
  })
  .then(function(v) {
    return Q(logAndIncrement(v));
  })
  .then(function(v) {
    console.log(v);
  });

// Slightly modified from https://github.com/kriskowal/q#sequences
function Qsequence(initialValue, promises) {
  var result = Q(initialValue);
  promises.forEach(function(r) {
    result = result.then(r);
  });
  return result;
}

// With Qsequence
Qsequence(0, [
  function(v) {
    return Q(logAndIncrement(v));
  },
  function(v) {
    return Q(logAndIncrement(v));
  },
  function(v) {
    console.log(v);
  }  
]);
