  12. * Run the functions in the `tasks` collection in series, each one running once
  13. * the previous function has completed. If any functions in the series pass an
  14. * error to its callback, no more functions are run, and `callback` is
  15. * immediately called with the value of the error. Otherwise, `callback`
  16. * receives an array of results when `tasks` have completed.
  17. *
  18. * It is also possible to use an object instead of an array. Each property will
  19. * be run as a function, and the results will be passed to the final `callback`
  20. * as an object instead of an array. This can be a more readable way of handling
  21. * results from {@link async.series}.
  22. *
  23. * **Note** that while many implementations preserve the order of object
  24. * properties, the [ECMAScript Language Specification](http://www.ecma-international.org/ecma-262/5.1/#sec-8.6)
  25. * explicitly states that
  26. *
  27. * > The mechanics and order of enumerating the properties is not specified.
  28. *
  29. * So if you rely on the order in which your series of functions are executed,
  30. * and want this to work on all platforms, consider using an array.

  37. * @param {Array|Iterable|Object} tasks - A collection containing

  39. * Each function can complete with any number of optional `result` values.
  40. * @param {Function} [callback] - An optional callback to run once all the
  41. * functions have completed. This function gets a results array (or object)
  42. * containing all the result arguments passed to the `task` callbacks. Invoked
  43. * with (err, result).
