裝飾者模式
// 有個Sale物件代表一筆銷售，呼叫`Sale.getPrice()`取得價格，額外的功能可以用`Sale.decorate()`附加至物件上
// 用法
var sale = new Sale(100); // 售價是100
sale.decorate('fedtax'); // 加上聯邦稅//"$112.88元
sale sale.decorate('quebec'); // 再加上魅北克省稅
sale.decorate('money'); // 格式化成金額
sale.getPrice(); // "$112.88"
sale = new Sale(100); // 售價是100元
sale.decorate('fedtax'); // 加上聯邦稅
