The TIOBE Index shows that there still is some interest in ActionScript, a programming language that you could say it’s another superset of JavaScript. And that’s a surprising thing, mainly because ActionScript’s purpose was the development of website and software with Adobe Flash Player components. As you might recall, Flash was a crucial element of the web some time ago, as it provided animations and interactive elements that couldn’t be done otherwise. However, with the arrival of HTML5, Flash fell from grace and now it’s mostly shunned. Basically, this all means that ActionScript is another one of those languages that will be gone sooner rather than later. 

A scripting language or script language is a programming language for a runtime system that automates the execution of tasks that would otherwise be performed individually by a human operator. Scripting languages are usually interpreted at runtime rather than compiled.
