In this chapter, we discussed the fundamentals of ActionScript 3.0. ActionScript is the ECMAScript-standard-based programming language used by Flex applications. Although the topic of ActionScript is far too complex to discuss comprehensively in one chapter, we have covered many of the basics you’ll need to get started writing ActionScript code, including where to place the code, basic syntax, common data types, how to write classes, the event model, error handling, working with XML, and reflection.
