AS1 and AS2 and AS3 all compile to Flash Player byte-code. The VM could not care less how you created the byte-code. You could define your own language and write your own compiler to generate an swf.

No one answered in a previous thread. But am I right in assuming unlike
AS2, AS3 won't compile down to AS1, therefore to take advantage of the
new 8.5 VM speed increases you will have to use AS3? AS2 will simply
give you flash 8 performance. This will obviously introduce a division
in the user base - those that dev/design for as2 and as3 and the apps
related to those. Will this division be mirroed in the IDE releases
(Basic, Web, Enterprise, Dev and who knows what else).

I think Flash's success is based on it's ease of use and it will be
interesting to see if the design community welcomes this paradigm shift,
or feels alienated by having to compromise and stick with the 'old tech'
Flash 8 VM.

Subject: RE: [Flashcoders] Learn AS2 or AS3?

Having read over AS2.0 and AS3.0 migration...

http://livedocs.macromedia.com/labs/1/flex/langref/migration.html


... it feels very disconcerning for those like myself who have invested a fair amount of time in AS2.0 only to find out that to take advantage of Flash Player 8.5+, one has to make massive migration changes to their AS2.0 code.

Take for example the MovieClip class. The methods that have been 'removed' show up frequently in a lot of what I have worked with like say 'attachMovie'

This is an interesting thread cause I wonder about the future of AS2.0 if it has a future.
