函数 Ember.computed() 和 function().属性() 有什么区别？

Question

App.Person = Ember.Object.extend({
  // these will be supplied by `create`
  firstName: null,
  lastName: null,

  fullName: function() {
    return this.get('firstName') + ' ' + this.get('lastName');
  }.property('firstName', 'lastName'),

  fullName:Ember.computed('firstName','lastName', function() {
     return this.get('firstName') + ' ' + this.get('lastName');    
  }
});

为什么有两种方法（函数）将函数声明为计算属性？有什么区别，好处？

Ember.computed() 是一个（干净的）alternative to function().property() in case you are disabling prototype extensions。
