|

| 19 | * Run the functions in the `tasks` collection in series, each one running once
|
||
| 20 | * the previous function has completed. If any functions in the series pass an
|
||
| 21 | * error to its callback, no more functions are run, and `callback` is
|
||
| 22 | * immediately called with the value of the error. Otherwise, `callback`
|
||
| 23 | * receives an array of results when `tasks` have completed.
|
||
| 24 | *
|
||
| 25 | * It is also possible to use an object instead of an array. Each property will
|
||
| 26 | * be run as a function, and the results will be passed to the final `callback`
|
||
| 27 | * as an object instead of an array. This can be a more readable way of handling
|
||
| 28 | * results from {@link async.series}.
|
||
| 29 | *
|
||
| 30 | * **Note** that while many implementations preserve the order of object
|
||
| 31 | * properties, the [ECMAScript Language Specification](http://www.ecma-international.org/ecma-262/5.1/#sec-8.6)
|
||
| 32 | * explicitly states that
|
||
| 33 | *
|
||
| 34 | * > The mechanics and order of enumerating the properties is not specified.
|
||
| 35 | *
|
||
| 36 | * So if you rely on the order in which your series of functions are executed,
|
||
| 37 | * and want this to work on all platforms, consider using an array.

|

| 47 | * @param {Function} [callback] - An optional callback to run once all the
