How to format an object of objects

I have this object

myObject = {
  id: "44",
  name: "name",
  firstName: "fn",
  lastName: "tt",
  cars: [],
  houses: [],
  family: {}
}

I want to format this object to 

myObject = {
  person: {
    id: "44",
    name: "name",
    firstName: "fn",
    lastName: "tt"
  },
  cars: [],
  houses: [],
  family: {}
}

Is there anyway i can do this without using delete?

You can destructure what you need, put the rest into a variable rest, and then re-assign myObject:

let myObject = {
  id: "44",
  name: "name",
  firstName: "fn",
  lastName: "tt",
  cars: [],
  houses: [],
  family: {}
}

const {id, name, firstName, lastName, ...rest } = myObject;

myObject = {
  person: { id, name, firstName, lastName },
  ...rest
}

console.log(myObject);

You can use destructuring:

const myObject = { id:"44", name:"name", firstName:"fn", lastName:"tt", cars: [], houses:[], family:{}}

const { houses, cars, family, ...rest } = myObject

const myNewObject = {
  person: rest,
  houses,
  cars,
  family
}
console.log(myNewObject)

You could create a new object and assign the properties to it:

let obj = { id:"44", name:"name", firstName:"fn", lastName:"tt", cars: [], houses:[], family:{}}

//I want to format this object to
//myObject = { person: {id:"44", name:"name", firstName:"fn", lastName:"tt"}, cars: [], houses:[], family:{}}

let res =  {}

res.person = {id: obj.id, name: obj.name, firstName: obj.firstName, lastName: obj.lastName}
res.cars = obj.cars
res.houses = obj.houses
res.family = obj.family

console.log(res)

You can use destructuring assignments to decompose your object into variables and restructure them in a simple function.

const format = (obj) => {
    const {id, name, firstName, lastName, ...props} = obj;
    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>
