Debugging is a part of every developer's job, and hopefully this chapter has shown you the tools and practices to best accomplish the task. The more code you write, and the more debugging you do, the better you will become. Just remember, the more planning and testing you do early on, the less debugging you'll likely have to do at the end. And always document your code.
This concludes this section of the book. The next section shows you how to begin incorporating external data into your projects.
