[javascript] Sort Array of object by object field in Angular 6

I am getting an array of "product"s from a resolver getting data from a json endpoint.

ngOnInit() {
  this.products = this._route.snapshot.data.products;
  console.log('products: ', this.products);

where one of the objects in this array is in the format

    "id": 3645,
    "date": "2018-07-05T13:13:37",
    "date_gmt": "2018-07-05T13:13:37",
    "guid": {
        "rendered": ""
    "modified": "2018-07-05T13:13:37",
    "modified_gmt": "2018-07-05T13:13:37",
    "slug": "vpwin",
    "status": "publish",
    "type": "matrix",
    "link": "",
    "title": {
        "rendered": "VPWIN"
    "content": {
        "rendered": "",
        "protected": false
    "featured_media": 0,
    "parent": 0,
    "template": "",
    "better_featured_image": null,
    "acf": {
        "domain": "SMB",
        "ds_rating": "3",
        "dt_rating": ""

What I want to do is sort this array by the field title.rendered

In olden times, in AngularJS, I would simply use an orderBy pipe in the template set to this field. Apparently, this is removed in Angular and from doing research it seems the preferred method is to sort the data itself, such as in ngOnInit.

But I can't figure out how to sort products by producs.title.rendered.

The answer is

You can simply use Arrays.sort()

array.sort((a,b) => a.title.rendered.localeCompare(b.title.rendered));

Working Example :

var array = [{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"VPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""},},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"adfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}},{"id":3645,"date":"2018-07-05T13:13:37","date_gmt":"2018-07-05T13:13:37","guid":{"rendered":""},"modified":"2018-07-05T13:13:37","modified_gmt":"2018-07-05T13:13:37","slug":"vpwin","status":"publish","type":"matrix","link":"","title":{"rendered":"bbfPWIN"},"content":{"rendered":"","protected":false},"featured_media":0,"parent":0,"template":"","better_featured_image":null,"acf":{"domain":"SMB","ds_rating":"3","dt_rating":""}}];_x000D_
array.sort((a,b) => a.title.rendered.localeCompare(b.title.rendered));_x000D_

Not tested but should work

 products.sort((a,b)=>a.title.rendered > b.title.rendered)

Try this

products.sort(function (a, b) {
  return a.title.rendered - b.title.rendered;


You can import lodash/underscore library, it has many build functions available for manipulating, filtering, sorting the array and all.

Using underscore: (below one is just an example)

import * as _ from 'underscore';
let sortedArray = _.sortBy(array, 'title');
