Yeah, problem with JavaScript function signatures is that every function argument is optional, including all the arguments you didn't write. In python those functions would look like: def F(a = None, b = None, *args): ... And you can't write any other kind of function in javascript. I don't really like that aspect of javascript, it creates so many hard to debug situations.
