+/**
+ * Creates an Observable that mirrors the first source Observable to emit a next,
+ * error or complete notification from the combination of the Observable to which
+ * the operator is applied and supplied Observables.
+ *
+ * ## Example
+ *
+ * ```ts
+ * import { interval, map, raceWith } from 'rxjs';
+ *
+ * const obs1 = interval(7000).pipe(map(() => 'slow one'));
+ * const obs2 = interval(3000).pipe(map(() => 'fast one'));
+ * const obs3 = interval(5000).pipe(map(() => 'medium one'));
+ *
+ * obs1
+ *   .pipe(raceWith(obs2, obs3))
+ *   .subscribe(winner => console.log(winner));
+ *
+ * // Outputs
+ * // a series of 'fast one'
+ * ```
+ *
+ * @param otherSources Sources used to race for which Observable emits first.
+ * @return A function that returns an Observable that mirrors the output of the
+ * first Observable to emit an item.
