Are you going to appear for an interview that has to do with Flash Actionscript? If yes, read these 10 most commonly asked Actionscript and flash related questions. I bet you will be asked at lease 3 of them.
1. What is the difference between _root and _level0?
_level0 : references the main Timeline of all swf.
_root : references the main Timeline in the level which loaded. Which means if you don’t have SWF within a SWF then _root and _level0 are the same. Otherwise _root is timeline for the main SWF file vs. _root is the timeline in the current level.
