What are the differences between JavaScript module patterns and classes?

JavaScript module patterns are used to encapsulate code and create private variables, while classes are syntactical sugar for creating objects 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 {
        publicMethod: function() {
            console.log(privateVar);
        }
    };
})();
MyModule.publicMethod(); // Outputs: I am private

How do classes handle inheritance?

Classes in JavaScript use the extends keyword to inherit from other classes. For example:

class Animal {
    speak() {
        console.log('Animal speaks');
    }
}
class Dog extends Animal {
    speak() {
        console.log('Woof!');
    }
}
const dog = new Dog();
dog.speak(); // Outputs: Woof!

Which one should I use for my project?

It depends on your project's needs. Use module patterns for encapsulation and private data, and classes for object-oriented programming and inheritance.
