Well firstly, Superpowers uses TypeScript out of the box and generates HTML and Javascript pages when you export it. HTML isn't actually a programming language so using JavaScript (which is a programming language) allows you to do all the cool fancy stuff.
First of all I think you should learn "actual" programming with JavaScript (TypeScript is just a different way of writing JavaScript). You can add cool stuff to any HTML pages you've made already with it. After that I'd take a look here http://docs.superpowers-html5.com/en/getting-start.... It's a good place to look in terms of tutorials. Checking out the documentation is useful and skill every programmer should have! There's also documentation from within the Superpowers editor which shows you how to use pretty much everything Superpowers provides.
Hope that helps you and don't give up on those dreams :D
