list an object's properties

[Herb]

how can I do that? I simply want to create a function which will list all
properties of any object which is supplied as an argument to the function

please disregard. After searching for 25 minutes, I found the answer 1
minute after posting my question. C'est la vie. <sigh>

var o = {}
for(att in o){
alert(o[att]);
}

var o = {}

thanks. What's the purpose of the above approach? Why not just do:
var o;

for(att in o){
alert(o[att]);
}
