## 🌟 Virus19 ðŸ¦
|
||
|
|
|
||
|
|
In the previous lessons you have seen some examples of values reassignement
|
||
|
|
along the way. Here are two more examples:
|
||
|
|
|
||
|
|
```js
|
||
|
|
let mainHouse = { door: 'blue' }
|
||
|
|
let acidHouse = { door: 'blue' }
|
||
|
|
|
||
|
|
mainHouse = 'destroyed'
|
||
|
|
acidHouse.door = 'red'
|
||
|
|
```
|
||
|
|
|
||
|
|
First, the object `mainHouse` has been replaced by the string `destroyed`.
|
||
|
|
|
||
|
|
Second, the door of `acidHouse` has been repainted with the color `red`.
|
||
|
|
|
||
|
|
You will now have to find a way to prevent this... A way of "freezing" your
|
||
|
|
objects if you will...
|
||
|
|
|
||
|
|
[Object.freeze](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/freeze)
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Level 4 Alert! A very smart `virus19` has escaped the laboratory! You have 5
|
||
|
|
mins to fight this virus on two fronts:
|
||
|
|
|
||
|
|
- First freeze the object `virus19` so that it cannot mutate!
|
||
|
|
- Then release the countermeasure by declaring `vaccine` which will be a secure
|
||
|
|
copy of the object `antivirus`.
