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

In Node.js, the "exports" and "module.exports" variables are used to export modules from a file.

"exports" is a shorthand alias for "module.exports". When you assign a value to "exports" within a module, you are actually modifying the "module.exports" object.

On the other hand, if you directly assign a new value to "module.exports", it will overwrite the entire "module.exports" object and the "exports" variable will no longer reference it.

Therefore, it is recommended to use "module.exports" when you want to export a single value or a function, and use "exports" when you want to export multiple values or functions.
