This website has been designed to inform and educate users about debugging. A range of excercises have been made
available to educate visitors about debugging. Debugging is the process of finding and fixing errors in your code pages.
This chapter shows you some tools and techniques you can use to debug and to analyze your site.
Debugging is the process of locating and fixing errors (known as bugs), in a computer program, or hardware device.
To debug a program or hardware device, you start with a known problem, isolate the source of the problem, and then fix it.
When someone says they have debugged a program, or "removed the bugs" in a program, they imply that they have fixed the program,
so that the bugs no longer exist in it. Debugging is a necessary process in almost any new software, or hardware development process,
whether a commercial product, an enterprise, or personal application program.
For complex products, debugging is done periodically throughout the development, and again during the customer beta test stages.
Because most computer programs and many programmed hardware devices contain thousands of lines of code, almost any new product is likely to contain a few bugs. Invariably, the bugs in the functions that get the most use, are found and fixed first.
