JavaScript JavaScript Foundations Arrays Methods: Part 2

JavaScript Foundations - Stage 4 Arrays - Methods 2 - Challenge Task 2 Not sure how to approach this?

The previous video showed us how to sort from smallest to largest in a numerical way. This challenge asks us to sort strings from smallest to largest. I get that we have to use the length property but even with that knowledge I'm having trouble with this. Any help would be appreciated.

Numerical Way

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

My Attempt

  saying2.sort(function(word) {
    return word.length;
  });
index.html 
<!DOCTYPE html>
<html lang="en">
  <head>
    <title> JavaScript Foundations: Arrays</title>
    <style>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
      }
    </style>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Arrays: Methods Part 1</h2>
    <script>
      var saying1 = ["The", "quick", "brown", "fox", "jumps", "over", "the", "lazy", "dog"];
      var saying2 = ["The", "quick", "brown", "fox", "jumped", "over", "the", "lazy", "dog's", "back"];
      saying1.reverse();
      saying2.sort(function(word) {
        return word.length;
      });
    </script>
  </body>
</html>

Hi Ivan,

Try this for the saying2 lines:

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

Hope that helps.

Thanks Rich,

That worked perfectly, I guess I should of taken the numerical example in the video literally. I remembered him saying the example would only work for numbers but your logic makes sense. Thanks again for the help.
