Deprecation Guide for Use defineProperty to define computed properties
Although uncommon, it is possible to assign computed properties directly to
objects and have them be implicitly computed from eg Ember.get
. As part of
supporting ES5 getter computed properties, assigning computed properties
directly is deprecated. You should replace these assignments with calls to
defineProperty
.
For example, the following:
let object = {};
object.key = Ember.computed(() => 'value');
Ember.get(object, 'key') === 'value';
Should be changed to:
let object = {};
Ember.defineProperty(object, 'key', Ember.computed(() => 'value'));
Ember.get(object, 'key') === 'value';
