Dealing with basic promises

promise.js

var promise = new Ember.RSVP.Promise(function(resolve, reject) {
  console.log('Promise is pending');
  
  setTimeout(function() {
    if (Math.random() < 0.7) {
       resolve({'status': 'ok'});
    }
             
    reject('Whoops, something went wrong');    
  }, 1000);
  
});

promise.then(function(response) {
  console.log(response);
}, function(error) {
  console.error(error);
});
