shift() and unshift()

This question needs to edited so that it conveys what is expected. In the context of "possibilities are endless" I would like jS expert to demonstrate how to use the two methods simultaneously. If not please change the wording to reflect you expectations succinctly.

Where in the challenge is it asking you to use those two methods simultaneously?

This is task 1 "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."

There isn't anything there to suggest you should use both methods together. shift() removes from the beginning and unshift() adds to the beginning.

What the challenge wants you to realize by "simultaneously" is that the shift() method does two things. It removes the first element from an array and also returns that element. So you could use it in an expression or in this case, assign it to a variable.
