getting the last item in a javascript object

Question

If I have an object like:

{ \'a\' : \'apple\', \'b\' : \'banana\', \'c\' : \'carrot\' }

If I don\'t know in advance that the list goes up

Answer 1

if you mean get the last key alphabetically, you can (garanteed) :

var obj = { 'a' : 'apple', 'b' : 'banana', 'c' : 'carrot' };
var keys = Object.keys(obj);
keys.sort();
var lastkey = keys.pop() // c
var lastvalue = obj[lastkey] // 'carrot'
