30 Chapter 2: CFML Basics
Commenting your code
As in other programming languages, it is important to include comments in your code. You
should comment your code for the following reasons:
• Commented code is easier to debug than code that is not commented.
• If you describe the code on the page, it is easier to make modifications.
• Commented code tends to be better organized.
Comment tag
The ColdFusion comment tag is similar to the HTML comment tag, except that it has three
dashes instead of two:
<!--- This is a CFML comment --->
ColdFuions comments can wrap to more than one line. ColdFusion comments are not returned
to the browser because the ColdFusion server processes and omits the comments from the page.
The user will never be able to read your comments.
