Using the share operator to turn cold Observables hot

share.ts

pokemon$ = http.get(/* make an http request here*/).pipe(share());
/*The pokemon$ Observable is now hot, we won't have multiple http requests*/

pokemon$
  .pipe(
    flatMap(pokemon => pokemon),
    filter(({ type }) => type === "Fire")
  )
  .subscribe(pokemon => {
    // Do something with pokemon
  });

pokemon$.pipe(switchMap(pokemon => getStats(pokemon))).subscribe(stats => {
  // Do something with stats
});
