Can you give an example of a module pattern?

Can you give me an example of a module pattern in JavaScript?

Sure! The module pattern is a design pattern that helps in encapsulating private variables and methods. Here's a simple example:

const Module = (function() {
    let privateVar = 'I am private';

    return {
        getPrivateVar: function() {
            return privateVar;
        },
        setPrivateVar: function(value) {
            privateVar = value;
        }
    };
})();

console.log(Module.getPrivateVar()); // Outputs: I am private
Module.setPrivateVar('New value');
console.log(Module.getPrivateVar()); // Outputs: New value

What are the benefits of using the module pattern?

The module pattern helps in organizing code, avoiding global scope pollution, and encapsulating private data. It promotes better maintainability and reusability.

Can you explain how it differs from other patterns?

Certainly! Unlike the revealing module pattern, which exposes only certain methods, the module pattern keeps most of the implementation private. This provides better control over the internal state.
