How do I get the value of a @ object attribute?

Question

So I'm getting some JSON data containing 12 objects. outputting the objects to console shows me:

Object{ (...) }
  @categoryID: "123"
  @id: "234"
  categoryTitle: "abc"
  (...)

If I want to fetch the category title, I simply do item.categoryTitle. But if I want the ID, I can't use item.id.

According to this answer, one can use $object->{'@id'};, but trying $item->{'@id'} is not working.

So how to I get this value?

If I understand your question correct I would go about using `item["@id"]` to get the value of @id. — hellozimi, Oct 31 '15 at 19:29

Refer it using ['key'] syntax

var obj = { '@id' : 123 };
console.log(obj['@id']);   //123

This is called bracket notation (as opposed to dot notation) – Paul S. Oct 31 '15 at 19:32
Thanks. Do you also know why they use the `@`? – Steven Oct 31 '15 at 20:37
I'm sorry. I am not sure why they have used `@` prefix. But using bracket notation all string literals are valid key. – rajuGT Oct 31 '15 at 20:41
