JS object access

Question

I have a js object and i'm trying to access it directly without having to do something like :

for(i in data) { obj = data[i] }

is there a better way to access this object without looping ? (i'll always have 1 result)

here is the firebug result for console.log(data) :

Are you aware of the key name that you want to access before trying to loop? — Mike Brant, Jan 17 '13 at 16:58
no i dont have access to the key name ... this is the user id that i'm returning . — commandos, Jan 17 '13 at 17:00
See [this](http://stackoverflow.com/a/5533324/538866) answer. `Object.keys[0]` would do it for all browsers, except IE8 and below. — Jonas G. Drange, Jan 17 '13 at 17:00

No, you can't access a property without knowing its name (aside from using fancy for-of-loops). And to get that name, you only can enumerate the properties with a for-in-loop or use Object.keys/….getOwnPropertyNames.

If you know that you always have exactly one key in your object, you might have chosen the wrong data structure.

in that specific case yes i get only 1 result because i'm using the same function that return all users . – commandos Jan 17 '13 at 17:09
