按属性重新命名变量(JavaScript）

在JavaScript代码中，我试图通过存储的数据重新命名对象。我试着按照这个网站的建议使用pathTo(http://thedesignspace.net/MT2archives/000381.html)，但我的控制台返回"ReferenceError:'pathTo'未定义"。我的代码看起来像这样：

// This code defines the Object constructor Card, used to make the card objects
var Card = function() {
    this.face = theFace(this);
    this.suit = theSuit(this);
    this.value = theValue(this);
};
// This code creates the Deck to be used.
var deck = [];
for ( i=0 ; i<52 ; i++ ) {
    deck.push( i );
};
for ( i=51 ; i>0 ; i-- ) {
    var random = Math.floor(Math.random()*i);
    var temp = deck[random];
    deck[random] = deck[i];
    deck[i] = temp;
};
// 0-12 is Spades.
// 13-25 is Hearts.
// 26-38 is Clubs.
// 39-51 is Diamonds.
// Now we create the hand of the player and dealer
var player = [];
var dealer = [];
// Now to deal a card to player
player.push(deck.pop());
dealer.push(deck.pop());
// and another
player.push(deck.pop());
dealer.push(deck.pop());
// function theFace gives the face of a card
function theFace( card ) {
    var faces = ["King","Ace","2","3","4","5","6","7","8","9","10","Queen","Jack"];
    return(faces[card%13]);
};
// function theValue uses 'switch' to determine points from a card
function theValue(card) {
    var value = card % 13;
    switch( value ) {
        case(0):
        case(11):
        case(12):
            value = 10;
            break;
        case(1):
            value = 11;
            break;
        default:
            value = value;
            break;
    };
    return value;
};
// function theSuit returns the suit of a card
function theSuit(card) {
    var suit;
    if(card>38) {
        suit = "Diamonds";
    }else if(card>25) {
        suit = "Clubs";
    }else if(card>12) {
        suit = "Hearts";
    }else {
        suit = "Spades";
    };
    return suit;
};
// function toObject the first (numbered) card of of a hand 
// and turns it into an Object with the desired properties
function toObject( hand ) {
    var card = hand.shift();
    if (typeof(card) !== "number") {
        hand.unshift(card);
    } else {
        var card = new Card ();
        card = pathTo[card.suit + card.face];
    };
    return hand;
};
console.log(player);
toObject(player);
toObject(player);
console.log(player);

我正在尝试将我正在转换的卡片从typeof==="number"重命名为typeof===="object"，这样当我多次运行代码（因此使用函数）时，手数组中的对象名称就不会重复。

以下是我的控制台正在打印的一些示例：

[ 19, 46 ]
ReferenceError: 'pathTo' is undefined

和

[ 31, 18 ]
ReferenceError: 'pathTo' is undefined

一定有办法做到这一点，我只是不知道怎么做。

在函数toObject中，我试图将手牌数组中的第一个数字（牌）转换为一个对象，将其限定符描述为标准52牌组的一张牌。编辑：我刚刚意识到我甚至没有把它推回去。我要试试看它是否有效。

editedit_SOLVED：我做到了！事实证明，我不需要更改名称，代码会以某种方式将其分离。我所需要做的就是：

更换

var Card = function() { 
    this.face = theFace(this); 
    this.suit = theSuit(this); 
    this.value = theValue(this); 
};

带有

var Card = function(card) {
    this.face = theFace(card);
    this.suit = theSuit(card);
    this.value = theValue(card);
};

和

function toObject( hand ) {   
    var card = hand.shift();   
    if (typeof(card) !== "number") {   
        hand.unshift(card);   
    } else {   
        var card = new Card ();   
        card = pathTo[card.suit + card.face];   
    };   
    return hand;   
};

带有

function toObject( hand ) {
    var card = hand.shift();
    if (typeof(card) !== "number") {
        hand.unshift(card);
    } else {
        var card = new Card (card);
        hand.push(card);
    };
    return hand;
};

谢谢你的帮助！
