按键对对象数组进行分组[重复]

Question

所以我有一个对象数组

const array = [
    {id: 1, name: "laptop", quality: "good"},
    {id: 2, name: "pc", quality: "good"},
    {id: 3, name: "laptop", quality: "bad"},
    {id: 4, name: "pc", quality: "bad"},
]

我如何将它分组以使其看起来像这样？

const result = {
    pc: [
    { id: 2, quality: "good"},
    { id: 4, quality: "bad"}
    ],
    laptop: [
    { id: 1, quality: "good"},
    { id: 3, quality: "bad"}
    ]
    }

Answer 1

const array = [
    {id: 1, name: "laptop", quality: "good"},
    {id: 2, name: "pc", quality: "good"},
    {id: 3, name: "laptop", quality: "bad"},
    {id: 4, name: "pc", quality: "bad"},
]
const grouped = {};
for (const { name, ...rest } of array) {
  if (!(name in grouped)) grouped[name] = [];
  grouped[name].push(rest);
}
console.log(grouped);
