Using .intersect functionality of Ember Computed Properties in component

sample-component.js

import Ember from 'ember';

export default Ember.Component.extend({
  selectedSkills: Ember.inject.service(),  // <-- service containing an array of objects.
  selected: Ember.computed.alias('selectedSkills.skills'), // <-- giving 'selected' nickname to this array of objects within service.
  skillsInCommon: Ember.computed.intersect('selected', 'project.skills'), // <-- returning only the objects present in both the service's array and in 'project.skills' (current model where this component is being called?)
});
