Ember._immediateObserver()

Specify a method that observes property changes.

Ember.Object.extend({
  valueObserver: Ember.immediateObserver('value', function() {
    // Executes whenever the "value" property changes
  })
});

In the future, Ember.observer may become asynchronous. In this event, Ember.immediateObserver will maintain the synchronous behavior.

Also available as Function.prototype.observesImmediately if prototype extensions are enabled.
