What is CommonJS in Node.js?
CommonJS is a module system that allows you to organize your JavaScript code into reusable modules in Node.js.
How do I create a module using CommonJS?
You can create a module by using module.exports
to export functions or variables, and require()
to import them.
Can you give me an example of a CommonJS module?

// math.js module.exports.add = function(a, b) { return a + b; };
// app.js const math = require('./math'); console.log(math.add(2, 3)); // Outputs: 5
