- * Delays the emission of items from the source Observable by a given timeout or
- * until a given Date.
- *
- * <span class="informal">Time shifts each item by some specified amount of
- * milliseconds.</span>
- *
- * <img src="./img/delay.png" width="100%">
- *
- * If the delay argument is a Number, this operator time shifts the source
- * Observable by that amount of time expressed in milliseconds. The relative
- * time intervals between the values are preserved.
- *
- * If the delay argument is a Date, this operator time shifts the start of the
- * Observable execution until the given date occurs.
- *
- * @example <caption>Delay each click by one second</caption>
- * var clicks = Rx.Observable.fromEvent(document, 'click');
- * var delayedClicks = clicks.delay(1000); // each click emitted after 1 second
- * delayedClicks.subscribe(x => console.log(x));
- *
- * @example <caption>Delay all clicks until a future date happens</caption>
- * var clicks = Rx.Observable.fromEvent(document, 'click');
- * var date = new Date('March 15, 2050 12:00:00'); // in the future
- * var delayedClicks = clicks.delay(date); // click emitted only after that date
- * delayedClicks.subscribe(x => console.log(x));
- *
- * @see {@link debounceTime}
- * @see {@link delayWhen}
- *
- * @param {number|Date} delay The delay duration in milliseconds (a `number`) or
- * a `Date` until which the emission of the source items is delayed.
- * @param {Scheduler} [scheduler=async] The IScheduler to use for
- * managing the timers that handle the time-shift for each item.
- * @return {Observable} An Observable that delays the emissions of the source
- * Observable by the specified timeout or Date.
- * @method delay
