Module Patterns vs Class Patterns

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

Module patterns are used to create private and public members, while class patterns are used to create 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 about a class pattern example?

Here's a basic class pattern example:

class MyClass {
    constructor(name) {
        this.name = name;
    }
    greet() {
        console.log(`Hello, ${this.name}!`);
    }
}
const obj = new MyClass('Alice');
obj.greet(); // Outputs: Hello, Alice!

Which pattern is better for large applications?

It depends on the use case. Module patterns are great for encapsulation, while class patterns are better for inheritance and object-oriented design.
