In this section we are going to go over multicasting. This occurs in instances where you may have multiple subscriptions being called at the same time.
Multicasting
Using the .pipe(shareReplay()) the multiple subscriptions can be shared and run together. This allows just one request to be sent to the server containing all the subscrition requests.
