Retrieve object based on variable key name

Question

How can I retrieve an object child using other variable.

The Code

var product = {
  '123':{
    'name':'Basket',
    'price':'12.30'
  }
}

var id = 123;

var basket_price = product.id.price;    // I want to use the id value
                                        // as the reference to
                                        // retrieve the object child

How is the correct way to achieve that? Apparently the above way is unsuccessful because I don't specify any child with the key name of 'id' in the object definition.

var product = {

    'price':'12.30'
  }
}

var id = 123;

var basket_name = product[id].name; 
alert(basket_name);
var basket_price = product[id].name; 
alert(basket_price);
