## 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"></button>

...adding
Click 1 --> <button class="button one"></button>
Click 2 --> <button class="button one two"></button>

...toggling `unpimp`
Click 3 --> <button class="button one two three unpimp"></button>

...and removing backwards
Click 4 --> <button class="button one two unpimp"></button>
Click 5 --> <button class="button one unpimp"></button>
Click 6 --> <button class="button"></button>
```

### Notions

- [`classList`](https://developer.mozilla.org/en-US/docs/Web/API/Element/classList): `add()`, `remove()`, `toggle()`

### Files

You only need to create & submit the JS file `pimp-my-style.js` ; we're providing you the following files to download (click right and save link) & test locally:

- the HTML file [pimp-my-style.html](./pimp-my-style.html) to open in the browser, which includes:

  - the JS script running some code, and which will also allow to run yours
  - 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`
