How to extract some of the items in an object?

Question

I'm trying to extract some of the items from an object. If I'm not wrong, I need to use for...in to loop the object items.

let myObject = {
  id: 1,
  company: "Apple",
  product: {
    name: "iPhone",
    price: "100",
    releaseDate: "01 Jan 2019",
    color: {
      black: "#000000",
      silver: "#C0C0C0",
    }
  }
}
for (property in myObject) {
  console.log(`${property} = ${myObject[property]}`);
}

How can I only get the product's name and price only?

Expected result:

newArray = [
    name: "iPhone",
    price: 100,
]

your expected output syntax as well as input is invalid. Also will you have a single product object or many — Shubham Khatri, Mar 26 '19 at 06:44

What you need is just Destructuring_assignment

let myObject = {
  id: 1,
  company: "Apple",
  product: {
    name: "iPhone",
    price: "100",
    releaseDate: "01 Jan 2019",
    color: {
      black: "#000000",
      silver: "#C0C0C0",
    }
  }
}


const {name, price} = myObject.product

console.log({name, price})

In case myObject is an array of object like @Hasan Sh mentioned. You can use reduce

let myObject = [
  {
  id: 1,
  company: "Apple",
  product: {
    name: "iPhone",
    price: "100",
    releaseDate: "01 Jan 2019",
    color: {
      black: "#000000",
      silver: "#C0C0C0",
    }
  }
},
{
  id: 2,
  company: "Samsung",
  product: {
    name: "galaxy S9",
    price: "100",
    releaseDate: "01 Jan 2019",
    color: {
      black: "#000000",
      silver: "#C0C0C0",
    }
  }
}

]

const rs = myObject.reduce((acc, e) => {
  const {name, price} = e.product
  acc.push({name, price})
  return acc
}, [])




console.log(rs)

I think what he meant is that the `myObject` is an object within an array?! `e.g. const data = [myObject, ...];` In that case loop through the `data` array and do TamDc's solution. — Hasan Sh, Mar 26 '19 at 06:55
