+/**
+ * Ignores source values for a duration determined by another Observable, then
+ * emits the most recent value from the source Observable, then repeats this
+ * process.
+ *
+ * <span class="informal">It's like {@link auditTime}, but the silencing
+ * duration is determined by a second Observable.</span>
+ *
+ * ![](audit.png)
+ *
+ * `audit` is similar to `throttle`, but emits the last value from the silenced
+ * time window, instead of the first value. `audit` emits the most recent value
+ * from the source Observable on the output Observable as soon as its internal
+ * timer becomes disabled, and ignores source values while the timer is enabled.
+ * Initially, the timer is disabled. As soon as the first source value arrives,
+ * the timer is enabled by calling the `durationSelector` function with the
+ * source value, which returns the "duration" Observable. When the duration
+ * Observable emits a value or completes, the timer is disabled, then the most
+ * recent source value is emitted on the output Observable, and this process
+ * repeats for the next source value.
+ *
+ * ## Example
+ *
+ * Emit clicks at a rate of at most one click per second
+ * ```ts
+ * import { fromEvent, interval } from 'rxjs';
+ * import { audit } from 'rxjs/operators'
+ *
+ * const clicks = fromEvent(document, 'click');
+ * const result = clicks.pipe(audit(ev => interval(1000)));
+ * result.subscribe(x => console.log(x));
+ * ```
+ * @see {@link auditTime}
+ * @see {@link debounce}
+ * @see {@link delayWhen}
+ * @see {@link sample}
+ * @see {@link throttle}
+ *
+ * @param {function(value: T): SubscribableOrPromise} durationSelector A function
+ * that receives a value from the source Observable, for computing the silencing
+ * duration, returned as an Observable or a Promise.
+ * @return {Observable<T>} An Observable that performs rate-limiting of
+ * emissions from the source Observable.
+ * @method audit
+ * @owner Observable

+ * Buffers the source Observable values, using a factory function of closing

+ * Opens a buffer immediately, then closes the buffer when the observable

+ * Emit an array of the last clicks every [1-5] random seconds
+ *
+ * ```ts
+ * import { fromEvent, interval } from 'rxjs';
+ * import { bufferWhen } from 'rxjs/operators';

+ * const buffered = clicks.pipe(bufferWhen(() =>

+ * `count` transforms an Observable that emits values into an Observable that
+ * emits a single value that represents the number of values emitted by the
+ * source Observable. If the source Observable terminates with an error, `count`
+ * will pass this error notification along without emitting a value first. If

+ * a value nor terminate. This operator takes an optional `predicate` function
+ * as argument, in which case the output emission will represent the number of
+ * source values that matched `true` with the `predicate`.
+ *
+ * ## Examples
+ *
+ * Counts how many seconds have passed before the first click happened
+ * ```ts
+ * import { fromEvent, interval } from 'rxjs';
+ * import { count, takeUntil } from 'rxjs/operators';
+ *
+ * const seconds = interval(1000);
+ * const clicks = fromEvent(document, 'click');
+ * const secondsBeforeClick = seconds.pipe(takeUntil(clicks));
+ * const result = secondsBeforeClick.pipe(count());
+ * result.subscribe(x => console.log(x));
+ * ```
+ *
+ * Counts how many odd numbers are there between 1 and 7
+ * ```ts
+ * import { range } from 'rxjs';
+ * import { count } from 'rxjs/operators';
+ *
+ * const numbers = range(1, 7);
+ * const result = numbers.pipe(count(i => i % 2 === 1));

+ *
+ * ![](debounceTime.png)
+ *
+ * `debounceTime` delays values emitted by the source Observable, but drops
+ * previous pending delayed emissions if a new value arrives on the source
+ * Observable. This operator keeps track of the most recent value from the
+ * source Observable, and emits that only when `dueTime` enough time has passed
+ * without any other value appearing on the source Observable. If a new value
+ * appears before `dueTime` silence occurs, the previous value will be dropped
+ * and will not be emitted on the output Observable.
+ *
+ * This is a rate-limiting operator, because it is impossible for more than one
+ * value to be emitted in any time window of duration `dueTime`, but it is also
+ * a delay-like operator since output emissions do not occur at the same time as
+ * they did on the source Observable. Optionally takes a {@link SchedulerLike} for
+ * managing timers.
+ *
+ * ## Example
+ * Emit the most recent click after a burst of clicks
+ * ```ts
+ * import { fromEvent } from 'rxjs';
+ * import { debounceTime } from 'rxjs/operators';
+ *
+ * const clicks = fromEvent(document, 'click');

+ * Convert an Observable of Notifications to an actual Observable
+ * ```ts
+ * import { of, Notification } from 'rxjs';

+ * const notifA = new Notification('N', 'A');

+/**
+ * Returns an Observable that emits all items emitted by the source Observable that are distinct by comparison from previous items.
+ *
+ * If a keySelector function is provided, then it will project each value from the source observable into a new value that it will
+ * check for equality with previously projected values. If a keySelector function is not provided, it will use each value from the
+ * source observable directly with an equality check against previous values.
+ *
+ * In JavaScript runtimes that support `Set`, this operator will use a `Set` to improve performance of the distinct value checking.
+ *
+ * In other runtimes, this operator will use a minimal implementation of `Set` that relies on an `Array` and `indexOf` under the
+ * hood, so performance will degrade as more values are checked for distinction. Even in newer browsers, a long-running `distinct`
+ * use might result in memory leaks. To help alleviate this in some scenarios, an optional `flushes` parameter is also provided so
+ * that the internal `Set` can be "flushed", basically clearing it of values.
+ *
+ * ## Examples
+ * A simple example with numbers
+ * ```ts
+ * import { of } from 'rxjs';
+ * import { distinct } from 'rxjs/operators';
+ *
+ * of(1, 1, 2, 2, 2, 1, 2, 3, 4, 3, 2, 1).pipe(
+ *     distinct(),
+ *   )
+ *   .subscribe(x => console.log(x)); // 1, 2, 3, 4
+ * ```
+ *
+ * An example using a keySelector function
+ * ```typescript
+ * import { of } from 'rxjs';
+ * import { distinct } from 'rxjs/operators';
+ *
+ * interface Person {
+ *    age: number,
+ *    name: string
+ * }
+ *
+ * of<Person>(
+ *     { age: 4, name: 'Foo'},
+ *     { age: 7, name: 'Bar'},
+ *     { age: 5, name: 'Foo'},
+ *   ).pipe(
+ *     distinct((p: Person) => p.name),
+ *   )
+ *   .subscribe(x => console.log(x));

+ * // { age: 4, name: 'Foo' }
+ * // { age: 7, name: 'Bar' }
+ * ```
+ * @see {@link distinctUntilChanged}

+ * Emits only the index of the first value emitted by the source Observable that
+ * meets some condition.
+ *
+ * <span class="informal">It's like {@link find}, but emits the index of the
+ * found value, not the value itself.</span>
+ *
+ * ![](findIndex.png)
+ *
+ * `findIndex` searches for the first item in the source Observable that matches
+ * the specified condition embodied by the `predicate`, and returns the
+ * (zero-based) index of the first occurrence in the source. Unlike
+ * {@link first}, the `predicate` is required in `findIndex`, and does not emit
+ * an error if a valid value is not found.
+ *
+ * ## Example
+ * Emit the index of first click that happens on a DIV element
+ * ```ts
+ * import { fromEvent } from 'rxjs';
+ * import { findIndex } from 'rxjs/operators';
+ *
+ * const clicks = fromEvent(document, 'click');
+ * const result = clicks.pipe(findIndex(ev => ev.target.tagName === 'DIV'));
+ * result.subscribe(x => console.log(x));
+ * ```
+ *

+ * @see {@link find}
+ * @see {@link first}
+ * @see {@link take}
+ *
+ * @param {function(value: T, index: number, source: Observable<T>): boolean} predicate
+ * A function called with each item to test for condition matching.
+ * @param {any} [thisArg] An optional argument to determine the value of `this`
+ * in the `predicate` function.
+ * @return {Observable} An Observable of the index of the first item that
+ * matches the condition.
+ * @method find
+ * @owner Observable
