Why doesn't .join() work with function arguments?

Question

Why does this work (returns \"one, two, three\"):

var words = [\'one\', \'two\', \'three\'];
$(\"#main\").append(\'
\' + words.join(\", \") + \'

I don't know if there's a simple way to convert arguments into an array, but you can try this:

var toreturn = "the list:";
for(i = 0; i < arguments.length; i++)
{
   if(i != 0) { toreturn += ", "; }
   toreturn += arguments[i];
}
