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>
