Populate array with objects attributes of an object literal

Question

I have some cards defined as objects within an object, e.g:

var cards = {
    s2: {suit: 4, rank: 2, name: '2 of spades'},
    s3: {suit: 4, rank: 3, name: '3 of spades'},
    //etc. 
};

I need them to be within an object, not an array.

I then need to create an array of certain length and populate it with cards.

Something along these lines:

var cardDeck = [];
for (i=0; i < 52, i++){
    cardDeck.push(???);
}

I tried to use for in loop and play with keys and even managed to push objects, but only {key} worked for me, unfortunately giving object containing only key value. How do I get whole objects pushed into cardDeck array?

you almost had, it, just loop through the objects by their keys, get each object from the key, and push it into the array

fiddle: https://jsfiddle.net/q3jaagcq/

var cards = {
    s2: {suit: 4, rank: 2, name: '2 of spades'},
    s3: {suit: 4, rank: 3, name: '3 of spades'},
    //etc. 
}; 

var cardDeck = [];

for (var key in cards) {
    var card = cards[key];
    cardDeck.push(card);
}

console.log(cardDeck);
