Sorting string from shortest to longest challenge

Can someone please help me with this challenge. I'm not sure how to sort them to show the shortest string to the longest string. The directions are as follows:

Sort the 'saying2' array, on about line 19, so that the words are listed in length order. The shortest first. Use the 'length' property on the strings in the sort function.

Thanks

saying2.sort(function(a, b) { return a.length - b.length; });

That should arrange the strings in ascending order or shortest to longest. And if you wanted to sort them from the longest to shortest, you would return b.length - a.length. Hope this helps!

Thanks Ben. How about for this challenge where it is asking me to return length for arrayCounter or 0 where there an undefined, string, or number value. I have this code but it isn't passing:

function arrayCounter (array) { if (typeof array === 'undefined', [1,2,3], 'string') { return 0;

      return array.length;
    }
  }

Hmmm, I'm not 100% sure about this but let's give this a shot.

Instead of using commas to separate your arguments 'undefined', [1,2,3], 'string'), try using the "or" operator ||. So it should look something like this:

function arrayCounter(array) { if (typeof array === 'undefined' || [1, 2, 3] || 'string') { return 0; }

Let's hope this works!
