Man, you sound pretty grumpy about it. I'm pretty sure that the author does not mean "just like Java but with no types". Python is all about the syntax (and it's certainly not all about "math-friendly" syntax), though the syntax was an interesting choice. "Fixing JavaScript" means different things to different people, but I take it to mean that crayon differs in some aspects that annoyed the author about JavaScript.

Notice that the author was rather effective at getting us to think about the features of these languages and how crayon fits in.
