I'm not saying Javascript is perfect. just that you can't draw many useful conclusions from a document that sets out to find specifically its weirdest (mis)features. And actually you could avoid using "typeof" by using polyfills/builtins for the new "is[Type]" range of functions in ecmascript5. or a similar one from a library.
