Remember Macro remembers values of properties first time that the macro is read.

ember-computed-remember

This addon provides computed property that remembers values at a specific point so that they could be restored later.

import rememberProperties from 'ember-computed-remember/properties';

var Elephant = Ember.Object.extend({
	// specify what properties to remember
	remembered: rememberProperties('age', 'name', 'color'), 
	// when would you like these properties to be remembered?
	remember: function() {
		this.get('remembered');
	}.on('init')
});

var jumbo = Elephant.create({
	name: 'Jumbo',
	age: 31,
	color: 'grey'
});

jumbo.set('name', 'Jumbo Sr');
jumbo.set('age', 80);

jumbo.get('name');
// > Jumbo Sr

jumbo.get('remembered.name');
// > Jumbo

// revert the values
jumbo.get('remembered').revert();

jumbo.get('name');
// > Jumbo
