Yes, I think it matters quite a bit. It would be very easy for someone, even in their right mind, to unintentionally have an extra comma somewhere in the middle of a long array literal and not notice it. And the compiler would not tell them, but instead would insert an empty element at that spot. I would prefer that the compiler require you to explicitly indicate each element in an array literal, for example:
var myList:Array = [1, 2, 3, undefined, 4, 5, 6]; Or, absent that, I would prefer that the documentation clearly spell out the behavior of extra commas in array literals. ________________________________ From: Paul A. <[email protected]> To: [email protected] Sent: Thursday, April 11, 2013 3:00 PM Subject: Re: [flexcoders] Array literals - odd behavior Does it really matter?
