I am a new developer ,

i have a problem about load json result in javascript

i have a javascript function to fetch data from API
and it was successfull

the result is like this

    "metadata": {
        "code": 200,
        "message": "OK"
    "response": {
        "data": {
            "Data": [
                    "Itemid": "11332",
                    "Userid": "3367",
                    "Username": "00202020",
                    "Firstname": "Ricki",
                    "Courseid": "10016",
                    "Shortname": "Kompetensi Inti",
                    "Itemname": "Introduction To Programming",
                    "Finalgrade": "8.00000"

how can i load it into table or list view in javascript

What I have tried:

var ListValue = "";
                   //Variable created to iterate the json array values.
               var i;
               //Generic loop to iterate the response arrays.
               for (i = 0; i < response.length; ++i) {
                   ListValue += "<li>" + response[i].Itemid + " --- " + response[i].Courseid

This is what i tried ,but response.length is undefined ,

how can i solve this?

Look at the JSON data: response isn't an array, Data is.
