+ * repeats for the next source value.

+ * 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.

+ * If called with no arguments, `first` emits the first value of the source

+ * emits the first value of the source that matches the specified condition. It
+ * may also take a `resultSelector` function to produce the output value from
+ * the input value, and a `defaultValue` to emit in case the source completes
+ * before it is able to emit a valid value. Throws an error if `defaultValue`
+ * was not provided and a matching element is not found.
+ *
+ * @example <caption>Emit only the first click that happens on the DOM</caption>
+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var result = clicks.first();
+ * result.subscribe(x => console.log(x));
+ *
+ * @example <caption>Emits the first click that happens on a DIV</caption>
+ * var clicks = Rx.Observable.fromEvent(document, 'click');
+ * var result = clicks.first(ev => ev.target.tagName === 'DIV');
+ * result.subscribe(x => console.log(x));
+ *
+ * @see {@link filter}
+ * @see {@link find}
+ * @see {@link take}
+ *
+ * @throws {EmptyError} Delivers an EmptyError to the Observer's `error`
+ * callback if the Observable completes before any `next` notification was sent.
+ *
+ * @param {function(value: T, index: number, source: Observable<T>): boolean} [predicate]
+ * An optional function called with each item to test for condition matching.
+ * @param {function(value: T, index: number): R} [resultSelector] A function to
+ * produce the value on the output Observable based on the values
+ * and the indices of the source Observable. The arguments passed to this
+ * function are:
+ * - `value`: the value that was emitted on the source.
+ * - `index`: the "index" of the value from the source.
+ * @param {R} [defaultValue] The default value emitted in case no valid value
+ * was found on the source.

+ *
+ * Re-emits all notifications from source Observable with specified scheduler.
+ *
+ * <span class="informal">Ensure a specific scheduler is used, from outside of an Observable.</span>
+ *
+ * `observeOn` is an operator that accepts a scheduler as a first parameter, which will be used to reschedule
+ * notifications emitted by the source Observable. It might be useful, if you do not have control over
+ * internal scheduler of a given Observable, but want to control when its values are emitted nevertheless.
+ *
+ * Returned Observable emits the same notifications (nexted values, complete and error events) as the source Observable,
+ * but rescheduled with provided scheduler. Note that this doesn't mean that source Observables internal
+ * scheduler will be replaced in any way. Original scheduler still will be used, but when the source Observable emits
+ * notification, it will be immediately scheduled again - this time with scheduler passed to `observeOn`.
+ * An anti-pattern would be calling `observeOn` on Observable that emits lots of values synchronously, to split
+ * that emissions into asynchronous chunks. For this to happen, scheduler would have to be passed into the source
+ * Observable directly (usually into the operator that creates it). `observeOn` simply delays notifications a
+ * little bit more, to ensure that they are emitted at expected moments.
+ *
+ * As a matter of fact, `observeOn` accepts second parameter, which specifies in milliseconds with what delay notifications
+ * will be emitted. The main difference between {@link delay} operator and `observeOn` is that `observeOn`
+ * will delay all notifications - including error notifications - while `delay` will pass through error
+ * from source Observable immediately when it is emitted. In general it is highly recommended to use `delay` operator
+ * for any kind of delaying of values in the stream, while using `observeOn` to specify which scheduler should be used
+ * for notification emissions in general.
+ *
+ * @example <caption>Ensure values in subscribe are called just before browser repaint.</caption>
+ * const intervals = Rx.Observable.interval(10); // Intervals are scheduled
+ *                                               // with async scheduler by default...
+ *
+ * intervals
+ * .observeOn(Rx.Scheduler.animationFrame)       // ...but we will observe on animationFrame
+ * .subscribe(val => {                           // scheduler to ensure smooth animation.
+ *   someDiv.style.height = val + 'px';
+ * });
+ *
+ * @see {@link delay}
+ *
+ * @param {IScheduler} scheduler Scheduler that will be used to reschedule notifications from source Observable.
+ * @param {number} [delay] Number of milliseconds that states with what delay every notification should be rescheduled.
