Module Patterns vs Classes: Which to Use?

What are the main differences between module patterns and classes in JavaScript?

Module patterns are used to create private and public members, while classes provide a blueprint for creating objects with shared methods.

Can you give me an example of a module pattern?

Sure! Here's a simple module pattern:

const MyModule = (function() {
    let privateVar = 'I am private';
    return {
        publicMethod: function() {
            console.log(privateVar);
        }
    };
})();
MyModule.publicMethod(); // Outputs: I am private

How do classes handle inheritance compared to module patterns?

Classes use the extends keyword for inheritance, allowing subclasses to inherit properties and methods from parent classes, while module patterns typically do not support inheritance directly.

When should I use module patterns instead of classes?

Use module patterns when you need encapsulation and want to create a singleton or a namespace. Classes are better for creating multiple instances with shared behavior.
