Comment

1. Text in a program's code, script or other type of file that is not meant to be seen by the user running the program. However, comment text can be seen by an individual viewing the code; this is often used to help understand what the code is performing. Comments allow for changes to be made or statements to be made about why something may have been done one way or another.
