JavaScript JavaScript Foundations Arrays Methods: Part 1

Problem with task

Is it just me or is there a conflict with the code in the third part of this task. My code passes for the first and second parts of the task, but when I try to complete the third part it says that the first part is no longer ok. Maybe because the variable we are asked to use is the same for both part one and part three?

Should someone else encounter this Problem, a possible solution would be:

var firstWord = spareWords.shift();
var lastWord = spareWords.pop();
saying.unshift(firstWord);

unshift() adds the element(s) which are passed to it (in the parentheses) to the beginning of the array it was called on, and returns the new length of said arraid.

In Stevens Code ("var firstWord = saying.unshift()") unshift() is called on "saying" and returns it's length, which is then assigned to "firstWord". This is why Task 1 isn't passing anymore.
