Hope this helps use x instead of customers,
customers refers to original array and and coustomers[key] will be undefined as customers array donot have any key with name custId or name
var customers = [{'custID': 123,'name': "ABC"},{'custID': 456,'name': "DEF"}]

for (x of customers) {
  for (key in x) {
    console.log(key + " = " + x[key])
var customers = [{'custID': 123,'name': "ABC"}, {'custID': 456,'name': "DEF"}]

for (x of customers) {
    console.log(`${key} = ${value}`)

should help you out You have to change your design. I'd like suggest to use Outer-Inner class and TreeSet.
class Foo {
 private String name;
 private TreeSet<Item> items;

 public Foo(String name) {
    this.name = name;
    items = new TreeSet<Item>();
 public String getName() { return name; }
 public void setName(String name) {this.name = name;}
 public TreeSet<Item> getItems() {return items; }
 public void addItem(Integer id, Integer value) {
    items.add(new Item(id, value));

 public class Item implements Comparable {
    public int compareTo(Object arg0) {
        Item i = (Item) arg0;
        if (id == i.id)
            return 0;
        else if (id > i.id)
            return 1;
            return -1;

    private Integer id;
    private Integer value;

    public Item(Integer id, Integer value) {
        this.id = id;
        this.value = value;

    public Integer getId() {
        return id;

    public void setId(Integer id) {
        this.id = id;

    public Integer getValue() {
        return value;

    public void setValue(Integer value) {
        this.value = value;
List<Foo> list = new ArrayList<Foo>();
list.add(new Foo("aa"));
list.add(new Foo("bb"));
list.add(new Foo("cc"));
list.add(new Foo("dd"));

list.get(0).addItem(1, 4);
list.get(0).addItem(2, 2);
list.get(0).addItem(3, 3);
list.get(1).addItem(3, 1);
list.get(1).addItem(1, 1);
list.get(1).addItem(2, 8);
list.get(2).addItem(3, 3);
list.get(3).addItem(2, 10);
list.get(0).addItem(5, 10);

for (Foo foo : list) {
 Foo.Item[] ar = foo.getItems().toArray(new Foo.Item[0]);
 for (int i = 1, j = 0; i <= 8; i++) {
   if (j >= ar.length)
    System.out.print(" - ");
   else if (ar[j].getId() == i) {
    System.out.print(" " + ar[j].getValue());
   } else
        System.out.print(" - ");

Iterate through JS object/array, and if you find a match change the value and return the original object/array structure

Tag : javascript , By : T11M

I wish this helpful for you I am trying to get a functionality like PHP in Javascript/Jquery, where we pass the address of a value (&$value) and edit its value in the actual array structure in PHP. For example I have a object in the following format, , This recursively applies a function to a nested object:
transform = function(obj, fun) {
    if (typeof obj != "object")
        return fun(obj);
    Object.keys(obj).forEach(function(k) {
        obj[k] = transform(obj[k], fun);
    return obj;
transform(yourData, function(val) {
    if (val.replace)
        return val.replace(/bad/g, "censored");
        return val;

it should still fix some issue I've been working with JS (ExtJS) for a while and I'm trying to do the following, assuming this array of objects: , You can do something like
var array = [{
  ticket: 'TICKET1',
  associated_val: 'AB'
}, {
  ticket: 'TICKET1',
  associated_val: 'XY'
}, {
  ticket: 'TICKET1',
  associated_val: 'CD'
}, {
  ticket: 'TICKET2',
  associated_val: 'YZ'
}, {
  ticket: 'TICKET2',
  associated_val: 'EF'
}, {
  ticket: 'TICKET3',
  associated_val: 'AB'
}, {
  ticket: 'TICKET4',
  associated_val: null

var newarray = [],
  tmp = {},
for (var i = 0; i < array.length; i++) {
  item = array[i];
  if (!tmp[item.ticket]) {
    tmp[item.ticket] = {
      ticket: item.ticket,
      associated_val_array: []
  if (item.associated_val != null) {

Angular 5: Iterate over [object].Array[object].[object].property with ngFor

Tag : angular , By : Robin Buitenhuis

may help you . You're setting the toplistByTotalVolume to equal the response in your subscription, which is an object that has the properties, Data, Message, SponserData, and Type. Then, each object in the Data array have the properties CoinInfo and ConversionInfo. So to display the name of each item, Iterate through the data of your toplistByTotalVolumeObject and access the name through the CoinInfo.
<ons-button (click)="getToplistByTotalVolume()">Aktualisieren</ons-button>
<ons-list id="crypto-container" *ngFor="let toplistByTotalVolumeItem of toplistByTotalVolume.Data;">
    <div class="center">
        {{ toplistByTotalVolumeItem.CoinInfo.FullName }}
getToplistByTotalVolume() {
    .subscribe(res => {
      this.toplistByTotalVolume = res.Data; //<--Here
      console.log(res); //<--This will log the entire response
      console.log(this.toplistByTotalVolume); //<--This will only log the `Data` property of the response, which is your array
<ons-list id="crypto-container" *ngFor="let toplistByTotalVolumeItem of toplistByTotalVolume;">
