Test drive

Even though there is plenty of work left to do, go ahead and take the coffee

maker for a test drive. Be sure you’ve added the sendRequest(), getSize(),

getBeverage(), and orderCoffee() functions to coffee.js, and then

load coffee.html in your web browser.

Enter in an order, and see what happens. Then, enter in another order... are

both coffee makers being used?

Jim’s large mocha

is brewing on the

rst coffee maker.

Bob’s order is

brewing over

on the seecond

coffee maker.

Notice that once an order is placed, the person’s name and

order details stay lled in. Could this cause problems? What

do you think we should do to avoid any confusion?
