Alternative to observers in Ember.js with ember-concurrency

wait-for-property-change.js

import { task, waitForProperty } from 'ember-concurrency';
import EmberObject from '@ember/object';

function waitForPropertyChange(object, prop) {
  const curValue = object.get(prop);
  return waitForProperty(object, prop, (newValue) => {
    return newValue !== curValue;
  });
}

EmberObject.extend({
  differentObserver: task(function* () {
    while(true) {
      yield waitForPropertyChange(this, 'someProperty');
      // do something
    }
  }).on('init')
});
