class js.html.Comment extends CharacterData
Available on js
A comment is used to add notations within markup; although it is generally not displayed, it is still available to be read in the source view (in Firefox: View -> Page Source). These are represented in HTML and XML as content between <!--
and --> .
In XML, the character sequence "--" cannot be used within a comment.
A comment has no special properties or methods of its own, but inherits those of CharacterData (which inherits from Node).
