What is the difference between module.exports and require in Node.js?

In Node.js, module.exports is used to export functions, objects, or variables from a module, while require is used to import them into another module.

Can you give me an example of how to use module.exports?

Sure! You can define a function in a file, say math.js, and export it like this: module.exports.add = function(a, b) { return a + b; };.

How do I import that function in another file?

You would use const math = require('./math'); and then call the function with math.add(2, 3);.

Are there any differences in how they work in ES6?

Yes, ES6 uses export and import syntax, which is more concise and allows for named exports and default exports.
