- * `interval` returns an Observable that emits an infinite sequence of
- * ascending integers, with a constant interval of time of your choosing
- * between those emissions. The first emission is not sent immediately, but
- * only after the first period has passed. By default, this operator uses the
- * `async` IScheduler to provide a notion of time, but you may pass any
- * IScheduler to it.
- *
- * @example <caption>Emits ascending numbers, one every second (1000ms)</caption>
- * var numbers = Rx.Observable.interval(1000);
- * numbers.subscribe(x => console.log(x));
- *
- * @see {@link timer}
- * @see {@link delay}
- *
- * @param {number} [period=0] The interval size in milliseconds (by default)
- * or the time unit determined by the scheduler's clock.
- * @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 sequential number each time
- * interval.
- * @static true
