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(\", \") + \'         


        

Answer 1

arguments is not a jQuery object, just a regular JavaScript object. Extend it before you try to call .join(). I think you would write:

return 'the list:' + $(arguments)[0];

(I'm not too familiar with jQuery, only Prototype, so I hope this is not completely bogus.)

Edit: It's wrong! But in his response, Doug Neiner describes what I'm trying to accomplish.
