===== Conditional Operator =====
JavaScript also contains a conditional operator that assigns a value to a variable based on some condition.

The syntax would be:HTML

<pre> variablename = ( condition ) ? value1 : value2 </pre>
''value1'' is the value of the expression if "''condition''" is fulfilled. ''value2'' is its value in the case "''condition''" is not fulfilled. 
For example:
<blockquote><code> var x = "Hello " + "world!" </code></blockquote>

{{Activity
| Repeat our activity with a conditional operator that assigns a value to a variable as shown below:

| <syntaxhighlight lang="html4strict">
<!DOCTYPE html>
<html>
        <head><title>Hello World, Again!</title></head>
 	<body>
 		<script type="text/javascript"></syntaxhighlight>
 			<syntaxhighlight lang="javascript">
                        var x = "hello"; 
                        var towrite = ( x == "hello")? "Hello world, again!" : "Look at the state of that!" 
                        document.write(towrite);

//The example results in "Hello world, again!" because x is "hello" and condition "Hello world, again!" is logically true. 
</syntaxhighlight>
                <syntaxhighlight lang="html4strict">
 		</script>


<p>
Save the document as helloToo.html and open it in a browser. 
Change the line var x = "hello" to var x = "punk" and use CRTL + S to save. 
Run it in your browser.
</p>
       </body>
</html>
</syntaxhighlight>
