JavaScript JavaScript Foundations Arrays Methods: Part 1

Challenge request is confusing. Several methods I have tried render different Bummer! results.

I have been getting results stating the 'firstWord' should be "The" when the request is to add the variable "firstWord" to the beginning and simultaneously remove it.

spareWord.unshift("firstWord"); spareWord.shift();

Then, it says method shift was not used. I have tried running this in console to see my mistake and it works fine but doesn't pass the challenge.

      var lastWord = spareWords;
      saying;

This is the challeng request: 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.

I think I understand what you are doing... Basically swapping the first word "The" for "firstWord". That makes more sense! Thanks!

Hey Cynthia,

I've went through the entire challenge and here are the methods you need. Just go through them one by one so you get an understanding of each of them.

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

The challenge request was confusing in that it stated simultaneously removing "it". It seemed as if I were to remove the variable I just added... which didn't make sense.
