It's kind of a shame this uses its own, probably more powerful, language instead of HyperTalk.
HyperTalk is one of the most accessible languages for beginners I've ever seen. Sure it was primitive and had somewhat weak data organization capabilities, but if you're like 6 it's pretty incredible for your experience to be:
1. Open a blank script
2. Drag a field on the screen and name it "myname"
3. Drag a button on the screen, open up it's script and see:
on mouseUp
end mouseUp
4. You then enter the following two lines between those two lines:
ask "What is your name?"
put it into card field myname
5. Then you go back and click the button and a dialog box appears asking your name and when you type it in an hit enter the name appears in the field you created.
That sort of directness is lost in modern development environments. The concept that the button's script lives inside of the button, and in fact everything on the page could have its own script. The page itself also has script, even the stack itself. Your code can of course call code in other objects if need be (typically at the page or stack level), and there is a whole message passing thing happening in the background. It's by far the most intuitive programming environment I've ever seen. It has the kind of immediate impact that helps to save off boredom or feeling like there's too much homework before the fun starts.
In the day people complained about the syntactic sugar in HyperTalk, but I think it was just right for the target audience. They did have more of a point about the difficulty in managing structured data, often having to store things in hidden fields referenced by line and word number or hacks like that.
The most incredible part is this was all in an application that came with the OS. It was the perfect opportunity for a bored kid to randomly come across it and discover a lifelong passion. There was nothing to install, no product to buy first--it was just there, asking to be discovered. And even if your parents weren't about to buy a reference book you could open up other stacks and start reading the code to learn the language. Because most scripts were small and self contained (remember that they were stored at the widget level) this was a legitimate way to understand the basic syntax and keywords.
