i dont no if this is handy but the link below should shed some light

I also added the link actionscript 2.0 vs 3.0 in related links
Hi friends,
I have written an article on actionscript 2.0 vs 3.0 before 2 yrs and continuously updating it. Plz click following link and read it:

Actionscript is a language used in macromedia flash. JavaScript is a web-based language that is used to make pages dynamic.
Flash MX uses ActionScript for its language. It controls the movies and the items inside the movies. ActionScript is similar to JavaScript, if you are familiar with JavaScript.
It would be harder to describe the similarity between JavaScript and XML. These two languages are for entirely different purposes.
Visual Basic script and JavaScript are both programming languages. JavaScript is used primarily to create websites, and has no user interface. Visual Basic is used to create software applications, has a user interface, and is less heavy on the code than JavaScript.
write() will just be a line of text and writeln() will be a line of text that puts the next writeln() on another line
AWT is a Java package for creating graphical user interfaces. JavaScript is a completely unrelated programming language.
The javascript editor is for the Flash Programming language called Actionscript. This is based on the ECMA guidelines that javascript is based on, therefore if you know javascript, Actionscript will be refreshingly easy to learn for you.
When you can choose between them, Javascript is better simply because it is an open standard supported by all browsers, while Actionscript is proprietary (owned by Adobe) and needs a browser plugin to run. Actionscript is unavoidable when working with Flash. Actually, to make this judgment based on Javascript being open source is too simplistic. Javascript is a prototyped language, and therefore is not truly object-oriented, which can make it slow and difficult to develop large applications in. Actionscript 3.0 is object-oriented and therefore can support complex design patterns and more robust applications. In addition, Javascript is rendered differently depending on the browser supporting it. Therefore, performance of Javascript applications varies widely. Because AS3 runs in the Flash player its performance is consistent across many devices.
Use the getURL() function to run javascript with the "javascript: " protocol. getURL("javascript: $('jquery code here');", "_self");

They are two completely different languages: with actionscript 3.0 it is more of a regular programming language.With actionscript 2.0, it is easier (in my opinion) because you don't have to refer to your movieclips and buttons and such in the actionscrpit, like you have to do in 3.0.
JavaScript and java are 2 completely different things. JavaScript is in web pages to make it more interesting and java is a complex computing language devised from c + c++.
JavaScript is a scripting language that is mainly used within a web browser. Jquery is a library of javascript code that can be used together with your javascript program. A set of functions that can preform common tasks is provided, which will reduce the amount of code that you have to write yourself.
No, it is not possible to put Actionscript 2.0 code in an Actionscript 3.0 code file. The Actionscript virtual machine that runs Actionscript 3.0 code is completely different from the Actionscript 1.0 and 2.0 virtual machine. The only way to include Actionscript 2.0 code in an Actionscript 3.0 project would be to have the Actionscript 3.0 Flash file load an external Actionscript 2.0 Flash file.
ActionScript 3 is the newer, quicker version of Adobe Flash's ActionScript. AS3, as Action Script 3 is normally called, is harder and more complicated for beginners, but much easier and more effective in the long run.
you can't. Dsi web browser isn't updateable. It is javascript based, and yes there is a difference between java and javascript. But you can still watch GIF videos on www.dsivid.webs.com
Without JavaScript (or a similar technology) HTML pages can't do much of anything. HTML does not contain any programming logic. This means that without another tool, all an HTML page can do is display the static content encoded within it, and collect form data to be sent to the server.JavaScript allows us to make a page react to the user. All web applications are based in JavaScript, or a similar language, for precisely this reason.HTML makes pages--like the pages in a book. The difference between a webpage and a paper page is entirely owed to JavaScript, VBScript and Actionscript.
DHTML combines HTML, JavaScript, the HTML DOM, and CSS.
