They are also experienced in developing cross-platform applications, which is a key advantage when developing RIAs. Additionally, Adobe Flex developers are typically well-versed in ActionScript, the programming language used to develop Adobe Flex applications. This allows them to create robust applications that can take advantage of all the features of the Adobe Flex platform.
