How does the module pattern work in TypeScript?

Can you explain how the module pattern works in TypeScript?

Sure! The module pattern is a design pattern that helps in organizing code into reusable modules. In TypeScript, it allows you to encapsulate variables and functions within a module, exposing only what is necessary.

What are the benefits of using the module pattern?

The benefits include better code organization, encapsulation of private variables, and avoiding global namespace pollution.

Can you show me a simple example of the module pattern in TypeScript?

Absolutely! Here's a basic example:

module MyModule {
    let privateVar = 'I am private';
    export function publicMethod() {
        console.log(privateVar);
    }
}

MyModule.publicMethod(); // Outputs: I am private

How does this differ from using classes in TypeScript?

The module pattern focuses on encapsulating functionality and state, while classes are more about creating objects with shared behavior. Modules can be used to group related functions and variables, whereas classes are used for creating instances.
