I remember when I first made the jump from ActionScript 2 to ActionScript 3.  I wasn't excited about the switch at the time.  I remember always asking myself why did they change this, I can't I do this anymore but after my first project I was happy I made the switch.  AS3 made coding easier.  I write less code in AS3 than I needed to do in AS2 with the exception of getURL.

I've been doing AS3 straight for the past year now.  Every time I have to start a new ActionScript project I always write it in AS3 for obvious reasons.  The challenge is when someone asked me to write a project that had to be done in AS2.  No AS3!  Sure, I thought, no problem. I have been coding for years in ActionScript 2 but wow how quickly I forget the differences.  I felt I had to reteach myself some of the basics.

The project should have only took me 4-6 hours but ended up taking me 8-10 hours.  If I could have wrote it in AS3 it probably would have took me just 2 hours.  Making the jump back seemed more difficult than the jump forward.  Some of the simplest actions I just forgot.  For example, assigning actions to buttons from my class.  It took me a moment to remember that inside the onClick function there is no true reference to the class, so I had to set one before I declared the action.  Simple code like that, which I used to write like clockwork, I just forgot. 

In all the change back was frustrating but kind of funny.  Seems like I need to do some more small AS2 projects on my own to stay sharp but if I have to do anything important I'm writing it in good new ActionScript 3.
