How do I implement CommonJS in Node.js?

To implement CommonJS in Node.js, you can use the require function to import modules and module.exports to export them.

Can you give me an example of how to export a function using CommonJS?

Sure! You can create a file named math.js and export a function like this:

function add(a, b) {
    return a + b;
}

module.exports = add;

How do I import that function in another file?

You can import the function in another file using require like this:

const add = require('./math');
console.log(add(2, 3)); // Outputs: 5

What are the advantages of using CommonJS?

CommonJS allows for modular code, making it easier to manage dependencies and maintain code. It also supports synchronous loading of modules.
