shift and unshift

The question says: "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." Anybody knows why it shows it incorrect?

JavaScript Foundations Arrays: Methods Part 1 
var spareWords = ["The","chimney","sweep's","dog"]; 
var saying = ["quick", "brown", "fox", "jumps", "over", "the", "lazy"]; 
spareWords.unshift('firstWord'); 
spareWords.shift(); 
var firstWord = spareWords; 
var lastWord = spareWords; 
saying; 
saying;

Something more like this is all you need, the question is worded strangely:

var spareWords = ["The","chimney","sweep's","dog"]; 
var saying = ["quick", "brown", "fox", "jumps", "over", "the", "lazy"]; 
var firstWord = spareWords.shift();
