## Pimp my style
### Instructions
Check out that button on the HTML page:
```html
< button class = "button" > pimp my style< / div >
```
For now, it's only a lonely, basic and sad element ; let's pimp it up!
On each click on the page, a function `pimp` is triggered.
Write the body of that function so that the button's class is altered:
- Add in order the next class of the `styles` array provided in the data file below
- When the end of the array is reached, remove backwards each class
- Toggle the class 'unpimp' when removing classes
```
Example for a `styles` array with only 3 classes:
Page load --> < button class = "button" > < / div >
...adding
Click 1 --> < button class = "button one" > < / div >
Click 2 --> < button class = "button one two" > < / div >
...toggling `unpimp`
Click 3 --> < button class = "button one two three unpimp" > < / div >
...and removing backwards
Click 4 --> < button class = "button one two unpimp" > < / div >
Click 5 --> < button class = "button one unpimp" > < / div >
Click 6 --> < button class = "button" > < / div >
```

- some CSS pre-styled classes: feel free to use those as they are, or modify them
- the data file [pimp-my-style.data.js ](./pimp-my-style.data.js ) from which you can import `styles`
