What are some examples of module patterns in JavaScript?

Module patterns in JavaScript are design patterns that help in organizing code and encapsulating functionality. Some common examples include the Revealing Module Pattern, the Immediately Invoked Function Expression (IIFE), and the CommonJS module pattern.

Can you explain the Revealing Module Pattern?

Sure! The Revealing Module Pattern is a way to structure your code so that you can expose only certain methods and properties while keeping others private. It uses an IIFE to create a private scope.

What are the benefits of using module patterns?

The benefits include better organization of code, encapsulation of functionality, and avoiding global namespace pollution. It also enhances maintainability and reusability.

Can you give me a simple code example of the Revealing Module Pattern?

Absolutely! Here's a simple example:

var myModule = (function() {
    var privateVar = 'I am private';
    function privateMethod() {
        console.log(privateVar);
    }
    return {
        reveal: function() {
            privateMethod();
        }
    };
})();

myModule.reveal(); // Outputs: I am private
