javascript - 如何为对象数组中的每个对象添加带有值的键？

Question

我有这个对象数组，我想以与 items 数组中相同的顺序添加下面对象的值，有什么建议吗？

const items = [{
    tshirt: "Model TS",
    jeans: "ModelXW",
  },
  {
    sneakers: "indcdsc54",
    furniture: "Table31S"
  },
  {
    dress: "indc54",
    short: "shortS2"
  },
];

对象或数组，哪个更容易？

const obj = [
  "localhost:8080.com",
  "localhost:3000.com",
  "localhost:7000.com",
]

预期输出：

const items = [{
    tshirt: "Model TS",
    jeans: "ModelXW",
    website: "localhost:8080.com",
  },
  {
    sneakers: "indcdsc54",
    furniture: "Table31S",
    website: "localhost:3000.com",
  },
  {
    dress: "indc54",
    short: "shortS2",
    website: "localhost:7000.com",
  },
];

我试过这种方法没有成功，有什么建议吗？

const items = [{
    tshirt: "Model TS",
    jeans: "ModelXW"
  },
  {
    sneakers: "indcdsc54",
    furniture: "Table31S"
  },
  {
    dress: "indc54",
    short: "shortS2"
  }
];

const obj = [
  "localhost:8080.com",
  "localhost:3000.com",
  "localhost:7000.com",
]

let newArray = obj.map(uri => items.map(i => i["website"] = uri ))

console.log(newArray)

像这样，假设uris在一个数组中

const items = [{
    tshirt: "Model TS",
    jeans: "ModelXW"
  },
  {
    sneakers: "indcdsc54",
    furniture: "Table31S"
  },
  {
    dress: "indc54",
    short: "shortS2"
  }
];

const uris = [
  "localhost:8080.com",
  "localhost:3000.com",
  "localhost:7000.com",
]

let newArray = items.map((item,i) => (item.website = uris[i], item)); 
// OR          items.map((item,i) => ({website : uris[i], ...item}));
console.log(newArray)
