## Modify an Object Nested Within an Object
|
||
|
|
Method:
|
||
|
|
- Remember the object you want to change is two levels deep, `dot-notation` is easier to use in this instance.
|
||
|
|
- Simply define the object and then use `dot-notation` to access the second object and finally the final element you wish to modify.
|
||
|
|
|
||
|
|
## Example:
|
||
|
|
```javascript
|
||
|
|
let myObject = {
|
||
|
|
level_1: 'outside',
|
||
|
|
first_level_object: {
|
||
|
|
level_2: '2 levels deep',
|
||
|
|
second_level_object: {
|
||
|
|
level_3: '3 levels deep'
|
||
|
|
}
|
||
|
|
}
|
||
|
|
};
|
||
|
|
//The following line of code will modify the data found in level_2.
|
||
|
|
myObject.first_level_object.level_2 = 'level-2 has been reached';
|
||
|
|
```
|
||
|
|
|
||
|
|
## Solution:
|
||
|
|
```javascript
|
||
|
|
let userActivity = {
|
||
|
|
id: 23894201352,
|
||
|
|
date: 'January 1, 2017',
|
||
|
|
data: {
|
||
|
|
totalUsers: 51,
|
||
|
|
online: 42
|
||
|
|
}
|
||
|
|
};
|
||
|
|
|
||
|
|
// change code below this line
|
||
|
|
userActivity.data.online = 45;
|
||
|
|
// change code above this line
|
||
|
|
|
||
|
|
console.log(userActivity);
|
||
|
|
```
