Javascript Short-Hand IF Within Object Notation

This isn't really a big thing here. For the first time ever, I tried using the Javascript IF statement short hand inside of an array call. I had no reason to think that this wasn't possible, it's just kind of cool to see it work:

  
          <script type="text/javascript">
        
          	// Create an array of friends.
        
          	var arrFriends = new Array(
        
          		"Molly",
        
          		"Sarah",
        
          		"Dave",
        
          		"Luke"
        
          		);
        
          	// Get the day of the week.
        
          	var intDayOfWeek = (new Date()).getDay();
        
          	// Figure out which friend to call based on
        
          	// the given day of the week. Call Luke on saturday.
        
          	// For every other day, call Molly (my girlfriend).
        
          	var strFriendToCall = arrFriends[ ( intDayOfWeek == 6 ) ? 3 : 0 ];
        
          </script>

When I am figuring out which index of the Friends array to call, I determine the value based on the day of the week. It's an IF statement inside of object notation. Again, nothing ground-breaking. Just neat.

@Jay,

Awesome stuff :)

Oh my chickens, this post is old!

Hit me up on Twitter if you want to discuss it further.

	<script type="text/javascript">

	// Create an array of friends.
	var arrFriends = new Array(
	"Molly",
	"Sarah",
	"Dave",
	"Luke"
	);

	// Get the day of the week.
	var intDayOfWeek = (new Date()).getDay();

	// Figure out which friend to call based on
	// the given day of the week. Call Luke on saturday.
	// For every other day, call Molly (my girlfriend).
	var strFriendToCall = arrFriends[ ( intDayOfWeek == 6 ) ? 3 : 0 ];
