ember.js - Who defines the "store" object? -

from code snippet :

todos.todoscontroller = ember.arraycontroller.extend({   actions: {     createtodo: function() {       // todo title set "new todo" text field       var title = this.get('newtitle');       if (!title.trim()) { return; }        // create new todo model       var todo = this.store.createrecord('todo', {         title: title,         iscompleted: false       });        // clear "new todo" text field       this.set('newtitle', '');        // save new model       todo.save();       }     } });
