sequence

Sequence
===

Creates an Asynchronous Stack which execute each enqueued method after the previous function calls the provided next(err, data [, ...]).

In many cases forEachAsync or forAllAsync will be a better alternative.

API
---

* Sequence.create(defaultContext=null)
* then(function callback(next, err, data [, ...]) {}, context) - add a callback onto the queue
* begins or resumes the queue
* passes the results of the previous function into the next

'use strict';

var Sequence = exports.Sequence || require('sequence').Sequence
, sequence = Sequence.create()
, err
;

sequence
.then(function (next) {
setTimeout(function () {
next(err, "Hi", "World!");
}, 120);
})
.then(function (next, err, a, b) {
setTimeout(function () {
next(err, "Hello", b);
}, 270);
})
.then(function (next, err, a, b) {
setTimeout(function () {
console.log(a, b);
next();
}, 50);
});

// so that this example works in browser and node.js
}('undefined' !== typeof exports && exports || new Function('return this')()));
