Methods Part 1: Elements task 3 -On about line 20, add the 'firstWord' variable to the beginning of the array 'saying'.

<script>

      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;

    </script>

I Tried adding

saying.unShift("firstWord");

i know this is wrong as we can't pass the variable with " ".

saying.unShift(firstWord);

passing the variable without " " 

saying.unShift(firstWord.toString());

everything displays the error You're missing the 'unshift' method and the 'firstWord' variable.

Try doing unShift without a capital S. Like this:

saying.unshift(the "firstWord" variable probablay goes here);

Thanks it works..! but why the method without camelcase, i didn't notice that while watching the video.

for the record, how many other methods or functions we have without camelcase.

To be honest I don't really know. The only reason I knew what to do for this one is because it said: 'unshift', not 'unShift'.

"unshift" does not use camel case because it is only one word. "Un" is a prefix of, not a separate word from, "shift."
