Commenting Your JavaScript

As with HTML and XML, you can add comments to JavaScript code; in JavaScript, you use a double forward slash (//) to start a comment. The JavaScript interpreter in the browser stops reading anything on a line past //, so you can comment your code like this:

<HTML> 
    <HEAD>
        <TITLE>
            Using Variables in JavaScript
        </TITLE>
    </HEAD>

    <BODY>
        <CENTER>
            <H1>
                Using Variables in JavaScript
            </H1>
        </CENTER>

        <SCRIPT LANGUAGE="JavaScript">
        <!--
            //Create the weatherReport variable
					var weatherReport
					//Assign a value to weatherReport
					weatherReport = "The temperature is 72 degrees."
					//Display the value in weatherReport
					document.writeln(weatherReport)
        //-->
        </SCRIPT>
    </BODY>
</HTML>
