JS should only target _js-_ prefixed classes. JS should never target styled classes.
JS may however check, add and remove state classes.

## Correct JS selectors:
```js
$('.js-openmenu').on('click', (btn) => { $(btn).addClass('is-open'); })
```

## Incorrect JS selectors:
```js
$('.menubutton').on(...)
```
