TRAINING ActionScript 3 - 2010 Calendar

Programming ActionScript 3 for Flex 3

Prerequisites

Knowledge of a programming language and of the concepts of programming objects.

Overview

ActionScript 3 is the new version of the programming language used for Flex 3 and Flash CS3 applications, as well as a powerful language for objects, introducing an important evolutionary step for the capacity of Flash Player 9 at runtime. Already from the first versions of ActionScript, the language offered developers power and flexibility for the creation of rich and interactive user experiences. With ActionScript 3, the language reaches a full maturity notably increasing the performance and the ease of the development of contents and applications used with Flash Player 9. The ActionScript 3 code is executed by the ActionScript Virtual Machine 2 (AVM2) inserted in Flash Player 9 that dramatically increases the performance and renders the rich internet applications up to 10 times faster compared to the previous version (AVM1).
ActionScript 3 is a language that bases itself on the standard international ECMAScript 262, Third edition, and contains functions that are based on Proposal 4 of the ECMAScript; it was designed to comply with the following programming requirements:

• Security: ActionScript 3 supports the security of types of data to permit developers to easily maintain the code
• Simplicity: ActionScript 3 is intuitive, and easy to write for programmers who have experience in languages such as Javascript, C# and Java
• Performance: ActionScript 3 allows you to write complex functions keeping the performance of the application high
• Compatibility: the language is based on standard ECMAScript and adds the capacity of ECMAScript for XML (E4X) evolving version 2 of ActionScript.

Training objectives

The course Programming ActionScript 3 for Flex 3 provides a deep knowledge of the language of ActionScript in its latest version used by Flex 3 for the programming side of rich internet applications.
