深度嵌套的 Arrays 和对象

Question

我正在尝试解构 object。 我想将一组对象放入作业中。 我必须对阵列进行减少吗？

我试图解构 object 但它只显示鞋子数组中的第一个 object。

const currentInventory = [
  {
    name: 'Brunello Cucinelli',
    shoes: [
      {name: 'tasselled black low-top lace-up', price: 1000},
      {name: 'tasselled green low-top lace-up', price: 1100},
      {name: 'plain beige suede moccasin', price: 950},
      {name: 'plain olive suede moccasin', price: 1050}
    ]
  },
  {
    name: 'Gucci',
    shoes: [
      {name: 'red leather laced sneakers', price: 800},
      {name: 'black leather laced sneakers', price: 900}
    ]
  }
];

for(var{name:designerName, shoes:[{name:shoeName,price}]} of currentInventory){
    console.log (designerName, shoeName, price)
}

Answer 1

你必须为shoes数组做另一个循环：

for (var { name: designerName, shoes } of currentInventory) {
  for (var { name: shoeName, price } of shoes) {
    console.log(designerName, shoeName, price)
  }
}
