I was wondering how to check an array for a blank index and removing it.

Right now I have this:  
[AS]  
function cleanArray (it)  
{  
for (var i = 0; i \< it.length; i++)  
{  
if (it \* == undefined)  
{  
it.splice (i, 1);  
}  
}  
}  
[/AS]

But it doesnt seem t work for me. What do you usually use?
