Refactoring

1:46 with Alena Holligan and Brian Retterer

At 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. 0:00
    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. 1:42
