This questions is too broad to give a truly appropriate
answer to. So, here is an incomplete list of differences
that you can use, and add to.
1.As3 is a compiled environment. Because of this,
operations in as3 can take up to 1/3 as long as they did in
as2. (according to adobe, and only if the code isn't on the
frame)
2.Because it's compiled we also get nice things like
compiler errors telling us when we've written some code that
won't compile properly, as2 just ignores these lines of
code. This can increase productivity significantly.
3.As3 uses a garbage collection system to clean up our
memory for us. (it doesn't really work, but at least it tries)
4.As3 is actually a different language. Some syntax remains
the same as in declaring variables, but almost all
functional operations have changed. Everything from how the
draw system works to adding an event listener are new.
