As3.0 completed the transition and used as3 for several Air programs.

After the transition from as2.0 to as3.0,
Familiar with class usage.
In fact, as2.0 transition mainly involves the event mechanism, displaying the list.
------------------------------------------
By reading help documentation,
I have a deep understanding of as3.
You can set the previous as2 Project
Integrated into as3.0.
------------------------------------------
As3 is the general trend,
Because it is more powerful and fully supported by object-oriented,
Code execution speed is 10 times faster than as2.
When compiling as3, when you try to use a normal statement in as2
For example, userNameTxt. text + = inputTxt. text;
Although there are no errors,
However, as3 will prompt you that this write method will reduce the speed,
And give your suggestions.
Currently, as has three versions: as1.0 (player 4), as2.0 (player 5 or above), and as3.0 (player 9 or above)
Also, the flash Lite version (Flash lite1.0, Flash lite 1.1 collectively referred to as Flash lite 1.X) uses the as1.0 syntax.
Flash lite 2.X also has the syntax of Flash lite 3.0 using as2.0.
Currently, no Lite version of as3.0 is supported.
Some days ago, I posted a post in the tiandihui, "Adobe Flash lite department stopped Lite R & D".
The reason is that Flash uses different codebase on different devices.
Flash on PC is a set of codebase and on mobile devices.
Of course, the test results for the above two devices are also different.
So currently, as3 is a standard language for Flash and all related products.

Air is the general trend, and Flex is just a transitional product of Air.
Air can only be developed using as3.
