如何格式化对象的对象

Question

我有这个对象

myObject = {

  id: "44",

  name: "name",

  firstName: "fn",

  lastName: "tt",

  cars: [],

  houses: [],

  family: {}

}

我想将此对象格式化为

myObject = {

  person: {

    id: "44",

    name: "name",

    firstName: "fn",

    lastName: "tt"

  },

  cars: [],

  houses: [],

  family: {}

}

无论如何我可以在不使用的情况下做到这一点delete吗？

Answer 1

您可以使用destructuring：const myObject = { id:"44", name:"name", firstName:"fn", lastName:"tt", cars: [], houses:[], family:{}}const { houses, cars, family, ...rest } = myObjectconst myNewObject = {  person: rest,  houses,  cars,  family}console.log(myNewObject)

Answer 2

您可以使用解构赋值将您的对象分解为变量并在一个简单的函数中重构它们。const format = (obj) => {&nbsp; &nbsp; const {id, name, firstName, lastName, ...props} = obj;&nbsp; &nbsp; return {person: {id, name, firstName, lastName}, ...props}}const formatted = format(myObject);console.log (formatted)<script>var myObject = { id:"44", name:"name", firstName:"fn", lastName:"tt", cars: [], houses:[], family:{}}</script>

Answer 3

您可以解构您需要的内容，将其余部分放入变量rest中，然后重新分配myObject：let myObject = {&nbsp; id: "44",&nbsp; name: "name",&nbsp; firstName: "fn",&nbsp; lastName: "tt",&nbsp; cars: [],&nbsp; houses: [],&nbsp; family: {}}const {id, name, firstName, lastName, ...rest } = myObject;myObject = {&nbsp; person: { id, name, firstName, lastName },&nbsp; ...rest}console.log(myObject);
