Courses Plus Student 2,589 PointsIt appears they are asking to unshift and shift simultaneously. I don't understand these instructions.
How can you unshift to the beginning of an array and then shift the element away in the same statement. Why would you even want to do this? It is possible I misunderstand the challenge: Javascript Foundations: Methods Part 1: Coding Challenge.

on line 18, you need to set the value of the firstWord var by calling the shift() method on the spareWords array. This will remove the first element from the spareWords array and return that value, thus setting the firstWord variable to the first element of spareWords, whilst simultaneously removing it from the array.
var firstWord = spareWords.shift();

Courses Plus Student 2,589 PointsI'm used to seeing words in single quotes as literal strings. Might it be easier to color code variables? Just a thought.

Courses Plus Student 2,589 PointsInstructions were as follows: 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.
Code: var spareWords = ["The","chimney","sweep's","dog"]; var saying = ["quick", "brown", "fox", "jumps", "over", "the", "lazy"]; var firstWord = spareWords; var lastWord = spareWords; saying; saying;
