// destructuring object & nested object & combine object into single object
let user = {
  name: 'Mike',
  friend: ["John", "Paul", "Jimmy"],
  location: {
    region:"England",
    country:"United Kingdom"
  },
  aboutMe: {
    status: "Single",
    pet: "Dog",
  }
}

const { name, friend, location, aboutMe: {status , pet} } = user;

console.log(name); // output: "Mike"
console.log(friend);  // output: [ 'John', 'Paul', 'Jimmy' ]
console.log(location); // output: { region: 'England', country: 'United Kingdom' }
console.log(status); // output: "Single"
console.log(pet); // output: "Dog"

//Combining Obj
const newUser = {
  ...user,
  car: {
    make: "Buick",
    year: 2012,
  }
}

console.log(newUser)
// output user obj + car object into one
// {
//   name: 'Mike',
//   friend: [ 'John', 'Paul', 'Jimmy' ],
//   location: { region: 'England', country: 'United Kingdom' },
//   aboutMe: { status: 'Single', pet: 'Dog' },
//   car: { make: 'Buick', year: 2012 }
