Чем паттерн “revealing module” лучше паттерна “module”?

let myMod1 = (function() { 
  let counter = 0; 
 
  console.log('myMod1'); 
 
  let increaseCounter = function() { 
    console.log('increaseCounter'); 
    counter++; 
  }; 
 
  let getCounter = function() { 
    console.log('getCounter'); 
    return counter; 
  }; 
 
  return { 
    getCounter: getCounter, 
    increaseCounter: increaseCounter 
  }; 
})();

let myMod2 = (function() { 
  let counter = 0; 
 
  console.log('myMod2'); 
 
  return { 
    increaseCounter: function() { 
      console.log('increaseCounter'); 
      counter++; 
    }, 
 
    getCounter: function() { 
      console.log('getCounter'); 
      return counter; 
    } 
  }; 
})();
