// first page (publish an event when a user is created)
function createUser(user) {
  console.log('User created!')
  events.publish('user:created', user, Date.now());
}

// second page (listen for the user created event)
events.subscribe('user:created', (user, time) => {
  // user and time are the same arguments passed in `events.publish(user, time)`
  console.log('Welcome', user, 'at', time);
});
