duplicate variable declaration
On page 108, the variable $new_comment is inadvertently declared with in two
var statements. It should only be declared above the if statement. The corrected
code looks like this:
var $new_comment;
if ($(".comment-input input").val() !== "") {
$new_comment = $("<p>").text($(".comment-input input").val());
$(".comments").append($new_comment);
$(".comment-input input").val("");
}
Thanks to Ken Hommel for reporting this.
