How can I pull a numerical value from a string in array and then use the .sort method so that I can pass along a functio

Function* . I know I'm suppose to use the .length to convert the string in the array a number, but a bit confused on how I do it .

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 (a.length,b.length){
        return a-b;
      });
    </script>
  </body>
</html>

You're really close... You need to access the 'length' property from inside the function.
