No, I am not aware that JavaScript functions can be overloaded.

But what you can do is to test for the existance of the arguments. This way, you could call a three-parameter function with fewer arguments and test whether the parameters were passed or not.
For example, let's say we define function xyz as:

You can call this function using any number of parameters. E.g.:

Any call you make with "missing" arguments will cause the corresponding parameters to evaluate as null.
Not as clean as overloading, but at least you can get the desired effect.
