var fighters = ['johnjones', 'rondarousey', 'connormcgregor', 'chuckliddel', 'demetriusjohnson'];
var warriors = {
wrestlers: ['randysavage', 'hulkhogan', 'ultimatewarrior', 'jakethesnake', 'milliondollarman'],
stable: [fighters, warriors.wrestlers]
}
I believe I can reference fighters from stable, but can I reference wrestlers from stable? In other words, how do I reference a key value pair from a later key value pair within the warriors object. Thank you for any and all help!
You cannot do that until the variable warriors is initialized. The only way is to wait and assign in the next line:
var warriors = {
wrestlers: ['randysavage', 'hulkhogan', 'ultimatewarrior', 'jakethesnake', 'milliondollarman'],
}
warriors.stable = [fighters, warriors.wrestlers]
Or use some kind of weird initialization like the one described here. Or use function constructor.
