+/**
+ * Returns an observable that will emit all values from the source, then synchronously emit
+ * the provided value(s) immediately after the source completes.
+ *
+ * NOTE: Passing a last argument of a Scheduler is _deprecated_, and may result in incorrect
+ * types in TypeScript.
+ *
+ * This is useful for knowing when an observable ends. Particularly when paired with an
+ * operator like {@link takeUntil}
+ *
+ * ![](endWith.png)
+ *
+ * ## Example
+ *
+ * Emit values to know when an interval starts and stops. The interval will
+ * stop when a user clicks anywhere on the document.
+ *
+ * ```ts
+ * import { interval, map, fromEvent, startWith, takeUntil, endWith } from 'rxjs';
+ *
+ * const ticker$ = interval(5000).pipe(
+ *   map(() => 'tick')
+ * );
+ *
+ * const documentClicks$ = fromEvent(document, 'click');
+ *
+ * ticker$.pipe(
+ *   startWith('interval started'),
+ *   takeUntil(documentClicks$),
+ *   endWith('interval ended by click')
+ * )
+ * .subscribe(x => console.log(x));
+ *
+ * // Result (assuming a user clicks after 15 seconds)
+ * // 'interval started'
+ * // 'tick'
+ * // 'tick'
+ * // 'tick'
+ * // 'interval ended by click'
+ * ```
+ *
+ * @see {@link startWith}
+ * @see {@link concat}
+ * @see {@link takeUntil}
+ *
+ * @param values Items you want the modified Observable to emit last.
+ * @return A function that returns an Observable that emits all values from the
+ * source, then synchronously emits the provided value(s) immediately after the
+ * source completes.
