Refactoring
1:46At this point, we have added a lot of new files, some of which have duplicate code. Let’s take some time to refactor them and make our code a little more manageable.
I don't know about you but I'm tired of
writing out the response for our system.

I want to do a little
refactoring in this video
0:05
to extract this out into its own function.
0:07
Refactoring improves the internal
structure of your code
0:10
without changing the external behavior.
0:13
If you find yourself writing the same
thing over and over, it's probably a good
0:16
indication that you have an area of code
that could benefit from refactoring,
0:21
making it easier to maintain that code
in the future in a lot of our files.
0:26
We have three lines that
are repeated all over the place.
0:31
Why don't we extract this into
a redirect you know functions file.
0:34
Let's copy the lines from
our vote.php file and
0:39
move them into our functions file.
0:42
We'll create a new function and
name it redirect.
0:46
Then we'll pass in the path.
0:52
Now we can change books.php to the path.
1:04
Now let's change the vote file to
substitute our new redirect function that
1:09
we just created.
1:13
Redirect to books.
1:22
And then remove the last two lines.
1:25
Let's test out our voting once more just
to make sure that everything still works.
1:28
Great.
1:38
Why don't you take the next
steps on your own and
1:39
change all of the three redirects
to our new redirect function.
