--description--

We need to provide a callback function in the parentheses of forEach().

This function will take each input item, in our case we'll call it input, as an argument. Then inside the function body, we need to call the remove() method.

In between the parentheses of the .forEach() function, enter input => input.remove().

--hints--

See description above for instructions.

assert(
  code.replace(/\s/g, '').match(/foodInputs.forEach\(input=>input.remove\(\)\)/)
);
