Comments

Use a comment to annotate or explain code within a script. Use the // token anywhere on a line to specify a single-line comment. All characters from the // token to the end of the line are ignored. Use an opening /* token and a closing */ token to specify a multi-line comment. Multi-line comments can start anywhere on a line, and all characters in between the /* token and */ token are ignored. A comment is included anywhere within a script.
