coffeemaker.php

What do we do with the server’s response?

You’ve completed orderCoffee(), and now coffeemaker.php is

done. When you send a request to brew coffee to one of the coffee makers,

coffeemaker.php runs and then returns the coffee maker that completed the

order, as well as the name of the person who placed the order.

The server returns the coffee maker that

nished brewing, and then the name of the

person who placed the order.

When the browser gets a response

from the server, it will run the

callback you indicated: serveDrink().

serveDrink() needs to let the person

who placed the order know their

coffee is ready, and set the status of

the right coffee maker back to “Idle”.
