--description--

We need a way to iterate through all the meal items in the total array and return the values that the user entered as an array.

The map() method allows us to do exactly that.

Delete const meal = total[0]; and chain the .map() method to the end of your Array.from() method. Here's an example of .map() chained to an array: [3, 2, 1].map()

--hints--

See description above for instructions.

assert(
  code
    .toString()
    .replace(/\s/g, '')
    .match(
      /Array\.from\(document\.getElementsByClassName\([\'\"\`]cal\-control[\'\"\`]\)\)\.map\(\)\;?/
    )
);
