Modules allow to create object in JS
In this case is creating an object named "worker" and is created by "createWorker" that return an object with 2 methods

var createWorker = function() {
  
  var count = 0;
  
  var job1 = function(){
    count +=1;
    console.log(count);
  };
  
  var task2 = function(){
    count +=1;
    console.log(count);
  };
  
  return {
     job1: job1,
     job2: task2
  };
  
};

var worker = createWorker();
worker.job1();
worker.job2();

  • IIFE
Immediately Invoke Function Expression

  • A function that it call itself
  • Avoid to create global variables


(function(){
 console.log("IIFE");
