Modify an Array Stored in an Object (freecodecamp notes)

So in this particular exercise we are given an user obj as below;

let user = {
  name: 'Kenneth',
  age: 28,
  data: {
    username: 'kennethCodesAllDay',
    joinDate: 'March 26, 2016',
    organization: 'freeCodeCamp',
    friends: [
      'Sam',
      'Kira',
      'Tomo'
    ],
    location: {
      city: 'San Francisco',
      state: 'CA',
      country: 'USA'
    }
  }
};

Exercise

Write a function that adds a new friend to friends array in the user obj
They provide us the following function structure

  function addFriend(userObj, friend) {
       // Only change code below this line

     // Only change code above this line
    }
  console.log(addFriend(user, 'Peter Gregory'));

	//Answer 1
	function addFriend(userObj, friend) {
	return userObj.data.friends.push(friend)
	}
	//Answer 2
	function addFriend(userObj, friend) {
	userObj.data.friends.push(friend)
	return userObj.data.friends
	}

Correct Answer? Answer 2

In attempt 1 we are returning what push function returns. Push returns the length of the array , instead of the array. Therefore we have to push the new friend and then return the array in the next line separately

Once you add Peter Gregory as a friend, remember to get him some asparagus!
