This is going to be fun. Really. To code is to debug. Ultimately, the thing that makes debugging stressful is when we’re not able to follow a consistent, disciplined process. This week, we’re going to fix that for you, giving you practice and perspective on debugging that you’ll be able to apply to coding and more.

Now, we’ll take a look at the core job of Controllers: automating things that computers are better at doing than humans. You’ll see how our case protagonist divests himself of the gruntwork it used to take to get demonstration data on their web application. Instead, he’ll write a Controller that dynamically creates HTML div’s (View elements) from a simple spreadsheet.

Here you go! This week, you’ll extend your work from course 1 on Views to integrated Views and Controllers. This will help you more fully internalize the four steps you’ve learned and, we hope, have some fun along the way.
