What is the Node.js module system?

The Node.js module system allows you to organize your code into reusable components called modules. Each module can export functions, objects, or variables, making it easier to manage dependencies.

How do I create a module in Node.js?

To create a module, you simply create a JavaScript file and use the module.exports syntax to export the desired functionality. For example, in myModule.js, you can write module.exports = function() { ... };.

What are CommonJS and ES6 modules?

CommonJS is the module system used by Node.js, where you use require() to import modules. ES6 modules use import and export syntax and are more modern, allowing for static analysis.

Can I use both CommonJS and ES6 modules in the same project?

Yes, you can use both, but you need to be careful with how you import and export them. You may need to use a transpiler like Babel for compatibility.
