Object 不在控制台日志中顯示值

Question

我的 class 對象未從控制台日志中的主 object 顯示

// Inventory , the main class

class Inventory{
    constructor(shoe,customer){
        this.shoes = [];
        this.customers = [];
    }

    addShoes(shoe){
        this.shoes.push(shoe);
    }

    addCustomers(customer){
        this.customers.push(customer);
    }
}

// Customer class

class Customer{
    constructor(name,address,phone){
        this.name = name;
        this.address = address;  
        this.phone = phone;
    }
}

//Shoes class

class Shoes{
    constructor(brand,name,color,size){
        this.brand =  brand;
        this.name = name;
        this.colors = [];
        this.sizes = [];
    }

    addColors(color){
        this.colors.push(color);
    }

    addSizes(size){
        this.sizes.push(size);
    }
}

// Where I put in the data for the object values, to display to console log

const inventory = new Inventory();

const myko = new Customer("Myko","216 Peachtree",9144444444);

const shoes = new Shoes("Nike","Air Force 1");
      shoes.addColors(["Black/Green","Blue/white","Red/Blue","White/Red"]);
      shoes.addSizes([12,10,9,11]);


const newAdd = new Inventory(shoes,myko);

console.log(newAdd);

我的控制台日志顯示的內容，空數據

庫存{鞋子：Array(0)，客戶：Array(0)} 客戶：Array(0)

當我在 console.log 中調用 Inventory class 時輸入數據時，我希望顯示控制台日志

庫存{鞋子：Array(1)，客戶：Array(1)}

客戶：“Myko”、“216 Peachtree”、9144444444”

鞋子：“Nike”、“Air Force 1”、“Black/Green”、“Blue/white”、“Red/Blue”、“White/Red”、12、10、9、11

Answer 1

您沒有使用構造函數中的參數初始化庫存。 （[] 反而。）

class Inventory{
    constructor(shoe,customer){
        this.shoes = shoe;
        this.customers = customer;
    }
