Problem assigning javascript object properties -

-

is there way assign object property pear below? (example doesn't work)

var fruitcolors = { apple: "green", pear: fruitcolors.apple};

i can achieve doing however, i'd like above if it's possible.

var fruitcolors = { apple: "green" }; fruitcolors.pear = fruitcolors.apple;

i don't think can - fruitcolors object doesn't exist @ time trying access it's property.
