Question

eg.

var myObject = {
    'item_123': {
        'id': 1,
        'name': 'Some name'
    },
    'item_789': {
        'id': 2,
        'name': 'Another name'
    }
};

The number part of the item attribute/object is not known before hand since they are unique ids and are auto generated. Is it possible to get item count from myObject without looping through it?

Answer 1

In modern browser,s you can use Object.keys:

 var objItemCount = Object.keys(myObject).length

For cross-browser support, you have to loop through the object, though.
