Introduction

ActionScript's place

ActionScript is also written in form of small code fragments, which are added to the Flash movie file. They are executed by Flash Player that is connected to the client browser. Even executing on client side ActionScript offers better security than traditional JavaScript or VBScript code because it's encapsulated into SWF Flash object and cannot be read by the user.

ActionScript is capable to work very effectively with native Flash objects like MovieClips, Buttons, Sounds. However it's capability to manipulate external environment components such as browser, history, navigator are restricted if compare to JavaScript and VBScript. So, ActionScript is considered mostly as "internal use" language, even if it's possible to refer to external JavaScript code it's a rare case. Communicating to server is used widely but didn't find it's niche in the "big" commercial Web programming yet.
