I'm claiming that its semantics are simple, not that they've made great choices in the design of the language. For example, I've barely used Javascript, but I think I would have scored fairly highly if that javascriptwft page was turned into a quiz. Most of the examples are fairly transparent once you know the implicit casting rules. I've read certain wtfs associated with C++ or even Java far more puzzling despite years of experience with them. And yes I do believe that writing an interpreter for Javascript would be no more difficult than doing one for Scheme (which I had to do as a student) - the parser would be more difficult admittedly.
