ActionScript 3: The Language of Flex Leading-Edge JavaActionScript 3: The Language of FlexA Conversation with James Ward, Part Iby Frank SommersApril 26, 2007 Summary Adobe announced this week that it would release the next version of its Flex SDK, Flex 3, under the open-source Mozilla license. The language used to create Flex applications is ActionScript 3, an object-oriented, functional programming language. Frank Sommers: What is ActionScript? James Ward: ActionScript 3 is our implementation of the ECMAScript 262, Revision 4 standard. We've done a few things differently from the ECMAScript standard, and the reason for that was that the standard wasn't actually finalized when we built Flash 9 and Flex 2. Frank Sommers: What will surprise a Java developer the most when first encountering ActionScript 3 code? The similar syntax allows Java developers to very quickly come up to speed by not having to really learn a brand new language. One of the biggest differences from Java is optional static typing in ActionScript 3.
