## Modify an Array Stored in an Object

### Method:

- The function can be written in just two lines of code.
- The first line should just use the `push()` function to add the `friend`parameter to the array found in `user.data.friend`. The second line will return the modified array.
- Remember that `user` mustb be referenced with the first parameter given to the `addFriend()` function.

### Solution:

```javascript

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'
    }
  }
};

function addFriend(userObj, friend) {
  // change code below this line  
  userObj.data.friends.push(friend);
  return userObj.data.friends;
  // change code above this line
}

console.log(addFriend(user, 'Pete'));

```
