Real-life: raceWith() cache vs network

The network is delayed, the cache is fast. With raceWith, the cache should win.

1. Solve the task in the editor — no long theory.
2. Run the check and compare your output with the expected result.
3. Stuck? Open the solution and carry the approach into your own code.

const { of, delay, raceWith } = Rx;

const network$ = of('network').pipe(delay(5));
const cache$ = of('cache');

const result$ = network$.pipe(
  raceWith(cache$)
);

result$.subscribe(value => console.log(value));
