+
+pubsub.subscribe('event', function (data) {
+  console.log(data);
+  // => Array [{fname: 'John'}, {lname: 'Doe'}, [1, 2, 3], 'Lorem ipsum dolor sit amet.']
+
+  console.log(data[0]);
+  // => Object {lname: 'John'}
+
+  console.log(data[1]);
+  // => Object {lname: 'Doe'}
+
+  console.log(data[2]);
+  // => Array [1, 2, 3]
+
+  console.log(data[3]);
+  // => String "Lorem ipsum dolor sit amet."
+});
+
+pubsub.publish('event', {fname: 'John'}, {lname: 'Doe'}, [1, 2, 3], 'Lorem ipsum dolor sit amet.');
