JavaScript JavaScript Foundations Strings Methods

Javascript method length, no parentheses?

Just wondering why the .length method in javascript doesn't require () when methods like .toUpperCase, .toLowerCase do?

index.html
<!DOCTYPE html>
<html lang="en">
  <head>
    <title> JavaScript Foundations: Strings</title>
    <style>
      html {
        background: #FAFAFA;
        font-family: sans-serif;
      }
    </style>
  </head>
  <body>
    <h1>JavaScript Foundations</h1>
    <h2>Strings: Methods</h2>
    <script>
      var quick = "The quick brown fox jumps over the lazy dog";

          var quickLength    = quick.length;
          var indexOfBrown = quick.indexOf("brown");
          var tenthCharacter = quick.charAt(9);
          var wordBrown = quick.substr(indexOfBrown, 5);
          var quickUpper = quick.toUpperCase();
          var quickLower = quick.toLowerCase();
    </script>
  </body>
</html>

HI John

Length is not a method, it is a property of the String object.

Oh right, long weekend, brain short out
