Writing Clean & Maintainable Code

What's the benefit of using the Module Pattern in JavaScript?

const UserModule = (function() {
  const privateData = [];

  function addPrivateUser(user) {
    privateData.push(user);
  }

  return {
    addUser: function(user) {
      addPrivateUser(user);
    },
    getUserCount: function() {
      return privateData.length;
    }
  };
})();

It makes the code execute faster
It reduces memory usage
It provides encapsulation and information hiding
The Module Pattern provides encapsulation and information hiding by creating a closure that contains private variables and methods. This pattern helps maintain clean and maintainable code by protecting internal implementation details and exposing only the necessary public interface. It's particularly useful for organizing code and preventing naming conflicts in larger applications.
