### Task

Yes, your eyes are no problem, this is toLoverCase (), not toLowerCase (), we want to make the world full of love.
    
### What do we need to do?
    
You need to add a prototype function to the String, the name is toLoverCase. Function can convert the letters in the string, converted to "L", "O", "V", "E", if not the letter, don't change it.
    
### How to convert? :

```
"love!".toLoverCase()="EVOL!"
```
