AS3 (ActionScript 3)

ActionScript 3.0 (AS3) is a programming language used primarily for creating interactive content, animations, and applications on the web, particularly within Adobe Flash. It allows developers to write code that controls the behavior of visual elements, such as buttons and graphics. AS3 is known for its improved performance and features compared to earlier versions, enabling more complex applications that can respond to user input, access data, and perform multimedia tasks. While Flash has largely been phased out, AS3 played a significant role in the development of rich internet applications in its time.
