Possible bug, or please correct me

Challenge: 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.

Error message: Bummer! The 'firstWord' should be the string of 'The'. It should be shifted from the 'spareWords' array.

my Solution:

var spareWords = ["The","chimney","sweep's","dog"];

spareWords.unshift("firstWord"); //adds "firstWord as the first element" console.log(spareWords.toString()); // result: firstWord,The,chimney,sweep's,dog

spareWords.shift(); //removes "firstWord as the first element" console.log(spareWords.toString()); //result: The,chimney,sweep's,dog

please explain why I'm not passing this challenge?

Thank you.

Ryan

Hi Ryan, The question is asking you to set the value of the variable "firstWord" to be the first word of the spareWords array, while also removing the first word from spareWords. This is the shift method. To do this, you only need to change the code on line 18, to var firstWord = spareWords.shift();. No other code changes are needed. When you don't set the result of calling the shift method on spareWords to a variable, that word is simply deleted. Hope that helps :) Sunshine and happiness, Laura
