Speaking of planning...
Looking for answers to the Be the Architect exercise back on
page 73? You’ll nd them... throughout this entire chapter.
As you read through the chapter, you’ll see how we decided to
build the Break Neck Pizza order app. See how your decisions match
up with ours, and think about how you might do things differently.
Sometimes, it’s better to do a little planning
before you jump in and start writing code. In
this case, we can go ahead and decide what
we’ll call the JavaScript function that makes a
request to the Break Neck server, even though
you haven’t started coding it yet. Let’s name this
function getCustomerInfo(), since that’s
exactly what the function is going to do: ask the
server for the customer’s information.
And now that you know the name of this
function, you can go ahead and update
the HTML in the Break Neck form to run
getCustomerInfo() when a phone number
is entered... even though you won’t code the
function for a few more pages.
Plan rst, code later
Aren’t you getting a little ahead of
things? How can we write an event
handler if we haven’t even written a
JavaScript function yet?
You might want to ip back to your
application blueprints on page 73,
and add the name of this JavaScript
function to your notes.
