javascript - Object internal reference declarations

I'm watching out for a shortcut way to use values from a dictionary as an internal reference inside the dictionary. The code shows what I mean:

var dict = {
    'entrance':{
        'rate1': 5,
        'rate2':10,
        'rate3':20,
    },

    'movies':{
        'theDarkKnight':{
            '00:00':<entrance.rate1>,
            '18:00':<entrance.rate2>,
            '21:00':<entrance.rate3>
        },
        ...
    };

is there a sneaky way to do this?

No. The best you can do is:

var dict = {
    'entrance' : {
        'rate1' : 5,
        'rate2' : 10,
        'rate3' : 20,
    }
};
dict.movies = {
    'theDarkKnight' : {
        '00:00' : dict.entrance.rate1,
        '18:00' : dict.entrance.rate2,
        '21:00' : dict.entrance.rate3
    },
    ...
};
