Module Patterns vs Class-Based Approach

What are the main differences between module patterns and class-based approaches in JavaScript?

Module patterns focus on encapsulation and creating private variables, while class-based approaches use prototypes and inheritance.

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 {
        getPrivateVar: function() {
            return privateVar;
        }
    };
})();

This creates a private variable that can't be accessed directly from outside the module.

How does inheritance work in class-based approaches?

In class-based approaches, inheritance allows a class to inherit properties and methods from another class using the extends keyword. This promotes code reuse.

Which approach is better for large applications?

It depends on the specific needs of the application. Module patterns can help with organization and encapsulation, while class-based approaches can simplify inheritance and polymorphism.
