AngularJS Question

Sorting an object by its value using lodash

I’m trying to sort an object alphabetically by its value using loadash only. My sample object is

var object = {AB:'apple',AC:'cat', AD:'bannana', BA:'atom'};

And i’m trying to get output as follows:

Object = {AB: "apple", BA: "atom", AD: "bannana", AC: "cat"}

I tried using _.sortBy, but it doesn’t seems to be working.

There is no such thing as sorting the properties of an object. An object is just an unordered set of key <-> property pairs.

You can create an array with the values of the object and sort them.

As explained in the lodash sortBy documentation, the sortBy method create a sorted array (ie. an ordered list) from the values of a collection. I am not sure that it fits your need. See the following snippet, that use your object as input value.

var object =  {AB:'apple',AC:'cat', AD:'bannana', BA:'atom'};
var sortedValues = _.sortBy(object, function(value) { return value; });
<script src=""></script>

Edit: From your comment, you need to get the (key, value) pairs to iterate over a list of pairs. Here is a proposed solution with a sorted array that is used in a ng-repeat directive.

angular.module('app', [])
  .controller('appCtrl', function($scope) {

    var object = {
      AB: 'apple',
      AC: 'cat',
      AD: 'bannana',
      BA: 'atom'

    var pairs =, function(value, key) {
      return [key, value];

    $scope.sortedPairs = _.sortBy(pairs, function(pair) {
      return pair[1]; // ie. value
<script src=""></script>
<script src=""></script>

<div ng-app="app">
  <ul ng-controller="appCtrl">
    <li ng-repeat="pair in sortedPairs">
      key: {{pair[0]}}, value: {{pair[1]}}
