/**
|
|
* 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.
