- * Creates an Observable that starts emitting after an `initialDelay` and

- * `timer` returns an Observable that emits an infinite sequence of ascending
- * integers, with a constant interval of time, `period` of your choosing
- * between those emissions. The first emission happens after the specified
- * `initialDelay`. The initial delay may be a {@link Date}. By default, this
- * operator uses the `async` IScheduler to provide a notion of time, but you
- * may pass any IScheduler to it. If `period` is not specified, the output
- * Observable emits only one value, `0`. Otherwise, it emits an infinite
- * sequence.
- *
- * @example <caption>Emits ascending numbers, one every second (1000ms), starting after 3 seconds</caption>
- * var numbers = Rx.Observable.timer(3000, 1000);
- * numbers.subscribe(x => console.log(x));
- *
- * @example <caption>Emits one number after five seconds</caption>
- * var numbers = Rx.Observable.timer(5000);
- * numbers.subscribe(x => console.log(x));
- *
- * @see {@link interval}
- * @see {@link delay}
- *
- * @param {number|Date} initialDelay The initial delay time to wait before
- * emitting the first value of `0`.
- * @param {number} [period] The period of time between emissions of the
- * subsequent numbers.
- * @param {Scheduler} [scheduler=async] The IScheduler to use for scheduling
- * the emission of values, and providing a notion of "time".
- * @return {Observable} An Observable that emits a `0` after the
- * `initialDelay` and ever increasing numbers after each `period` of time
- * thereafter.
- * @static true
- * @name timer
