For example, a person's contact information can be represented in JSON as follows:

contact::=
{
    "firstName": "John",
    "lastName": "Smith",
    "age": 25,
    "married": true,
    "address": {
        "streetAddress": "123 Main Street",
        "city": "New York",
        "state": "NY",
        "postalCode": "10021"
    },
    "email": [ "jsmith@yahoo.com", "jsmith@gmail.com" ],
    "phoneNumber": [
        {
            "type": "home",
            "number": "212 555-1234"
        },
        {
            "type": "fax",
            "number": "646 555-4567"
        }
    ]
}

It can be deserialized into object by JavaScript's eval()

  var p = eval("(" + contact + ")");

or JSON's parse()

  var p = JSON.parse(contact);
