Accessing object within object in JavaScript

Question

var obj = {{
    data: {
        type: 'string',
        value: 'bir'
    },
    field: 'red'
    },
    {
    data: {
        type: 'string',
        value: 'bir'
    },
    field: 'green'
    }
};

How do you manipulate the data s.

Answer 1

As an objects array it could be valid :

var obj = [{
    data: {
        type: 'string',
        value: 'bir'
    },
    field: 'red'
    },
    {
    data: {
        type: 'string',
        value: 'bir'
    },
    field: 'green'
    }
];

But then again some context would be welcome ^^
