First introduced in Flash Player 9, ActionScript 3 is an object-oriented programming (OOP) language based on ECMAScript—the same standard that is the basis for JavaScript—and provides incredible gains in runtime performance and developer productivity. ActionScript 2, the version of ActionScript used in Flash Player 8 and earlier, continues to be supported in Flash Player 9 and Flash Player 10.
