What programming language is specifically designed for animation on websites?

ActionScript is a programming language that was specifically designed for use with Adobe Flash and Adobe Animate. It enables developers to create interactive animations and manage multimedia content effectively on the web. This language is particularly tailored for controlling animations, handling user interactions, and making dynamic changes to graphics on the screen.

JavaScript is also widely used for animation on websites and is integrated into HTML5, but it is a general-purpose programming language that serves a broader range of functionalities beyond just animations. Python, while powerful and versatile, is not specifically designed for web animation; it is more commonly used in backend development and data analysis. HTML, on the other hand, is the markup language used for structuring web content but does not provide the programming capabilities needed for animated interactions.

Therefore, ActionScript stands out as the language explicitly designed for creating animations in environments like Adobe Animate, making it the correct answer for this question.
