  39. * Creates an Observable that starts emitting after an `initialDelay` and
  40. * emits ever increasing numbers after each `period` of time thereafter.
  41. *
  42. * <span class="informal">Its like {@link interval}, but you can specify when
  43. * should the emissions start.</span>

  47. * `timer` returns an Observable that emits an infinite sequence of ascending
  48. * integers, with a constant interval of time, `period` of your choosing
  49. * between those emissions. The first emission happens after the specified
  50. * `initialDelay`. The initial delay may be a {@link Date}. By default, this
  51. * operator uses the `async` IScheduler to provide a notion of time, but you
  52. * may pass any IScheduler to it. If `period` is not specified, the output
  53. * Observable emits only one value, `0`. Otherwise, it emits an infinite
  54. * sequence.
  55. *
  56. * @example <caption>Emits ascending numbers, one every second (1000ms), starting after 3 seconds</caption>
  57. * var numbers = Rx.Observable.timer(3000, 1000);
  58. * numbers.subscribe(x => console.log(x));
  59. *
  60. * @example <caption>Emits one number after five seconds</caption>
  61. * var numbers = Rx.Observable.timer(5000);
  62. * numbers.subscribe(x => console.log(x));
  63. *
  64. * @see {@link interval}
  65. * @see {@link delay}
  66. *
  67. * @param {number|Date} initialDelay The initial delay time to wait before
  68. * emitting the first value of `0`.
  69. * @param {number} [period] The period of time between emissions of the
  70. * subsequent numbers.
  71. * @param {Scheduler} [scheduler=async] The IScheduler to use for scheduling
  72. * the emission of values, and providing a notion of "time".
  73. * @return {Observable} An Observable that emits a `0` after the
  74. * `initialDelay` and ever increasing numbers after each `period` of time
  75. * thereafter.
