Iterate throght a JSON string
===

I have a JSON like this

     var json =  '{ "Comments": 
        [
          { "Id" : 1,"Comment" : "Test comment","Name" : "Yogesh","Child" : 0},
          { "Id" : 2,"Comment" : "Test comment II","Name" : "Yogesh","Child" : 0}
        ] 
        }';

    var parsedJSON = $.parseJSON(JsonData);

    var html = "";    
    for (comment in parsedJSON.Comments) {
      html += "Id: " + comment.Id;
      html += "Comment: " + comment.Comment;
      html += "Name: " + comment.Name;
      html += "Child: " + comment.Child;
      html += "<br/>";
    }


But here `comment` in for loop becomes 0 and 1 only, I mean not an object but just a string, how can I iterate through this JSON ??
