JavaScript JavaScript Foundations Strings Methods

string methods

here is my challenge <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(10, 5);
      var quickUpper = quick.str.toUpperCase();
      var quickLower = quick;
</script>

why is quickUpper causing my error message to say task one is no longer working?

          var tenthCharacter = quick.charAt(9);
          var wordBrown = quick.substr(10, 5);
          var quickUpper = quick.str.toUpperCase();
          var quickLower = quick;
    </script>

Hi Norman,

You have extra code here - var quickUpper = quick.str.toUpperCase();

It should be - var quickUpper = quick.toUpperCase();

You are calling the toUpperCase method on a string, in this case quick.

Thanks, you were right. I'm going to work more with strings to improve. Norm
