FlashCoders,
I've recently been upgrading some old Flash MX code to Flash 8, and have
been running into issues where properties return 'undefined' instead of
'null'. I seem to recall that undefined was introduced in Flash 7. I've
always been confused about when something is undefined versus null, so I
always check for both. { (var != undefined && var != null) }
Is there an explanation somewhere regarding the difference between undefined
and null, and when to expect which? If not, can someone who understands
explain it?
Thanks in advance!
