Javascript Programming Tutorials, Guides & Best Practices

The Module Pattern is one of the most common design patterns in JavaScript. It allows you to encapsulate private and public variables and methods, providing a clean and organized way to manage your code.

const MyModule = (function() {
    // Private variables and functions
    let privateVariable = 'I am private';

    function privateFunction() {
        console.log(privateVariable);
    }

    // Public API
    return {
        publicVariable: 'I am public',

        publicFunction: function() {
            privateFunction();
        }
    };
})();

console.log(MyModule.publicVariable); // Output: I am public
MyModule.publicFunction(); // Output: I am private
