ember.js - Ember-CLI: Initializers and and Initializer subclass -

currently, in ember-cli initializer defined so:

// app/initializers/observation.js export default {   name: 'observation',   initialize: function() {     // code   } };

in case, how define sub-class of initializer... following code correct?

// app/initializers/close-observation.js export default ember.observation.extend{   newproperty: 1,   otherproperties: 2 };

just import base initializer variable , extend that.

 import observation './observation';   export default observation.extend{    newproperty: 1,    otherproperties: 2  };
