Hi Ranjen,

I had the same problem and then figured it out with trial and error. Try re-wording the challenge question to something like this:

"On line 18, remove the first word from the spareWords array and store that value into the variable firstWord."

Can you figure it out from here?

Hi Robert thans for the help but still haven't fixed it. Did you mean like this ?

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

Hint: You don't need to unshift anything.

Ok i fixed it with this :

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

Thanks Robert :)

Yes you are right Robert , actually the answer is just this line :

var firstWord = spareWords.unshift("firstWord");

Thanks again :)
