var cards = {
    heart:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    spade:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    diamond:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
    king:[2, 3, 4, 5, 6, 7, 8, 9, 10, "joker", "queen", "king", "ace"],
};

var category = "spade";
var value = 3;
var index = cards[category].indexOf(value);

cards[category].splice(index, 1);

console.log(cards);
