//var sum = 0;
arr.forEach(function (value, index, array){  // Built in method
    //sum += value;
    console.log(value, index, array);
})

//console.log(sum);  // We can print sum of all Array element (if those are numbers)

// function forEach(arr, cb){  // How forEach() method works
//     for (var i = 0; i<arr.length; i++){
//         cb(arr[i], i, arr);
//     }
// }
// var sum = 0;
// forEach(arr, function (value, index, arr){
//     console.log(value, index, arr);
//     sum += value;
// })
// console.log(sum);

detail = "<ul>";
result.params.detail.forEach((val) => {
  detail = detail + sprintf(lang.pay_credit_detail, val.credit, val.expiry_date);
});
detail += "</ul>";

$('#pay_credit_remain').html(detail);
