It isnt possible to add arguments to a function that takes no arguments in javascript

I saw a funny piece of code on a seemingly professional webdesign website in my town.(Well it really is). I am not going to name it incase any of you are out there on boards.

Anyway the website uses Macromedias built in javascript functions to play around with the images.

The function was mm_preLoadImages() ..... No Arguments.

The company must of thought the javascript magically accepts arguments from a non argumented function such as above.

They added 5 or 6 arguments.

You see javascript is one pain in the h**** to decipher problems with. I know so well. It actually dosent give out any errors if you add arguments unlike any other languages I know of C for example.

If I am wrong please tell me but I really dont think that Javascript can take no existent arguments;

Another thing I see in many scripts online is this "<!-- //-->" so called hack which was origionally intended for first generation browsers Netscape 1 and mosaic and can actuall can errors as javascript complies the "HTML" comments.
