# --description--
Later we will want to remove these extra `calorieInput` elements that we added. This will happen when the user pushes the "Clear" button.
To keep track of them, add the class name `extra-cal-control` to the `calorieInput` element.
# --hints--
See description above for instructions.
```js
assert(
code
.replace(/\s/g, '')
.match(/calorieInput\.classList\.add\([\'\"\`]extra-cal\-control[\'\"\`]\)/)
);
```
