Array Set Challenge

Does anyone understand understand this question:

On line 18, use a method on the 'spareWords' to set 'firstWord' to be first word of the 'spareWords' array whilst simultaneously removing it from the beginning of the array.

<script>
      var spareWords = ["The","chimney","sweep's","dog"];
      var saying = ["quick", "brown", "fox", "jumps", "over", "the", "lazy"];
      var firstWord = spareWords;
      var lastWord = spareWords;
      saying;
      saying;
    </script>

I can't understand what there after?

Hi Douglas,

This task wants you to remove the word "The" from the beginning of the spareWords array and also assign that word to the firstWord variable.

The shift() method will remove the first element from an array and it will also return that element. Which means you can then assign that return value to a variable.

var firstWord = spareWords.shift();
