javascript - 我该如何使其更加“复杂”？

Question

首先，我刚刚开始自己​​学习JS，没有任何编程经验，这意味着我仍然要了解这种出色的编程语言的基本构建模块。

我的问题与我编写的以下代码有关：

  let orderCount = 0;

    const takeOrder = (size, beverage, milk, flavouring) => {
      console.log("Order: A " + size + " " + beverage + " made of " + milk + " with added " flavouring");
    orderCount++
    };

    const getTotal = (itemCount) => {
    return itemCount * 1000;
    };

    takeOrder('large', 'latte', 'soy milk', 'caramel syrup');
    takeOrder('medium', 'cappuchino', 'coconut milk', 'vanilla syrup');
    takeOrder('small', 'latte macchiato', 'lactose free milk', 'sugar-free hazelnut syrup');


    console.log(getTotal(orderCount));

如您所知，这是关于接受订单。目前，每笔订单的价格为1000（匈牙利福林），这是我想要更改的价格。我的意思是，例如，如果某个订单包含椰子奶，那么我想将价格提高160。

您可以使用object作为价格，这很容易扩展。

const takeOrder = (size, beverage, milk, flavouring) => {
    console.log("Order: A " + size + " " + beverage + " made of " + milk + " with added " + flavouring);
    total += data[beverage][size] + (data[milk] || 0) + (data[flavouring] || 0);
    //                                          ^^^^ use a default value if the key does
    //                                               not exist in the object or is falsy
    orderCount++;
};

var data = {
        latte: {
            large: 1000
        },
        cappuchino: {
            medium: 1000
        },
        'latte macchiato': {
            small: 1000
        },
        'coconut milk': 160
    },
    orderCount = 0,
    total = 0;

takeOrder('large', 'latte', 'soy milk', 'caramel syrup');
takeOrder('medium', 'cappuchino', 'coconut milk', 'vanilla syrup');
takeOrder('small', 'latte macchiato', 'lactose free milk', 'sugar-free hazelnut syrup');

console.log(orderCount);
console.log(total);
