Chapter 4. Code Structure That Eases Debugging

AS THE POPULAR SAYING GOES,“AN OUNCE of prevention is worth a pound of cure.”This statement is quite true when it comes to software development, especially for the Internet. If you take the time to plan and build your web applications in a structured and organized way, you can accomplish two things. First, you reduce the number of bugs that are introduced into your code (namely, the ones caused when you complicate things to the point of absolute confusion). Second, when you do encounter bugs in your code, you will be able to find and eliminate them much more easily. This chapter is designed to help you create your code in an organized fashion, as well as give you a foundation on which to debug your web application after it is built.
