We have already seen that building Flex applications often involves a combination of components and ActionScript. We have tried to keep the ActionScript in our examples simple and clear, but as the interaction becomes more complex, so does the ActionScript involved. Now is a good time to look at ActionScript 3.0 and to familiarize yourself with some of the ActionScript that we will be working with in the next few chapters. The intention of this chapter is not to make you a developer or to teach programming, but to give you an understanding of how ActionScript works and relates to the components. This will ultimately make you a better Flex designer.
