    console.log(dateTimeFormat2.format(dateformat));

    console.log(dateTimeFormat1.format(dateformat));

    const dateTimeFormat3 = new Intl.DateTimeFormat('en-US', Geeks);

                new Date(2012, 03)];
    var geeks = { year: 'numeric', month: 'long' };

    var dateTime = new Intl.DateTimeFormat('hi', geeks);
    var result = list.map(dateTime.format);
    console.log(result.join(' <-> '));

    var dateTime1 = new Intl.DateTimeFormat('tr', geeks);
    var result1 = list.map(dateTime1.format);
    console.log(result1.join(' ; '));

    var dateTime2 = new Intl.DateTimeFormat('LT', geeks);
    var result2 = list.map(dateTime2.format);
