扑克游戏中的支票、下注或弃牌功能问题(javascript）

我对Javascript很陌生，对我的一个函数（checkOrBet）有疑问。我正在尝试制作一款德州扑克游戏，而似乎不起作用的部分是我测试常规对的地方。当牌被发到牌组时，它似乎没有意识到已经制作了一对。

function game() {
    function Playert(name, chips) {
        this.name = name;
        this.chips = chips;
        this.firstCard = [];
        this.secondCard = [];
        this.blind = {};
        // this.turnpos = 0; //1 for current turn 
        //will be computer's response when prompted during the flop
        this.checkOrBet = function checkOrBet() {
            var response;
            //Ace High
            if (this.firstCard.rank == "A") {
                    response = "call";
                    console.log("Ace High!");
            } else if (this.secondCard.rank == "A") {
                    response = "call";
                    console.log("Ace High!");
            }
            //Tests for a pocket pair
            if (this.firstCard.rank == this.secondCard.rank) {
                response = "call";
                console.log("Pocket pairs!");
            }
            //Test for a regular pair 
            if (this.firstCard.rank == communityCards.cards[0].rank || communityCards.cards[1].rank || communityCards.cards[2].rank) {
                response = "call";
                console.log("pairs");
             } else if (this.secondCard.rank == communityCards.cards[
                            0]) {
                 response = "call";

             }
