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.
