What are some examples of module patterns in JavaScript?

There are several module patterns in JavaScript, including the Revealing Module Pattern, the Module Pattern, and the IIFE (Immediately Invoked Function Expression). Would you like to know more about a specific one?

Can you explain the Revealing Module Pattern?

Sure! The Revealing Module Pattern is a way to structure your code to keep certain variables and functions private while exposing only the parts you want to be public. It uses an IIFE to create a scope.

Can you give me a 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 {
        publicMethod: function() {
            privateMethod();
        }
    };
})();

myModule.publicMethod(); // Logs: I am private

What are the benefits of using module patterns?

Module patterns help in organizing code, avoiding global namespace pollution, and encapsulating functionality, which leads to better maintainability.
