EmberError vs. native Error

controllers.application.js

import Ember from 'ember';
import EmberError from '@ember/error';

const NativeError = Error;

export default Ember.Controller.extend({
  appName: 'Ember Twiddle',
  
  emberError: Ember.computed(function() {
    return new AdapterError('test');
  }),
  
  nativeError: Ember.computed(function() {
  	return new NativeAdapterError('test');
  })

  this.isAdapterError = true;
  EmberError.call(this, message);

  this.errors = errors || [
    {
      title: 'Adapter Error',
      detail: message,
    },
  ];
}

AdapterError.prototype = Object.create(EmberError.prototype);

// Native Error
