L oop через JSON массив с JavaScript

Question

Я загружаю JSON с URL-адреса, я хотел бы создать al oop через массив субъектов в попытке и вывести каждый itemName. Однако он продолжает выдавать ошибки, я новичок в работе как с JavaScript, так и с JSON, поэтому, возможно, я ошибаюсь. Будем признательны за любые советы!

JavaScript код

<script>
        getUrl();
            
        //Get the Url with current date + current time
        function getUrl() {

        var dateObj = new Date();
        var month = ("0" + (dateObj.getMonth() + 1)).slice(-2);
        var day = ("0" + dateObj.getDate()).slice(-2);
        var year = dateObj.getFullYear();
        var hours = dateObj.getHours();
        var minutes = dateObj.getMinutes();
        var seconds = dateObj.getSeconds();

        var currentdate = "";
        currentdate = year + "-" + month + "-" + day + "T" + hours + ":" + minutes + ":" + seconds;

        var currenttime = "";
        currenttime = hours + minutes + seconds;

        var url = "http://snowautomation.msbb.uc.edu/API/schedule/getAval.sh?" + currentdate;
        console.log(url);
        loadJSON(url);   
            
        }
            
        //Load the JSON from the url
        function loadJSON(url) {
            
            fetch(url)
                .then(res => res.json())
                .then((out) => {
                parseData(out);
                })
                .catch(err => { throw err });
        }
        
            
        function parseData(json) {

            try {
                for (var i = 0; i < results.length; i++) {
                    for (var prop in result[i]) {
                        if (result[i].itemName[enter image description here][1](prop)) {
                            alert(result[i][prop]);
                        }
                    }
                }
            
                console.log(json);
        
            }
            catch {
                console.log("error");
            }
        }   
</script>
