## 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',
|
||
|
|
