Node.js includes server functions. You don't need Apache/PHP, IIS/ASP, or any other web server/language product combination like those. This makes node.js deployments small, fast, and easy to scale.

Express is widely used instead of raw node.js because node.js provides only low-level tools for handling network requests. Express is middleware that provides basic server features on top of node.

Express provides easy to use built-in, semantic methods like app.get() and app.post(). You can code these yourself in raw node.js if you want to eliminate any middleware overhead that might impact the performance of your node.js application, and in some applications this may be necessary. But for the most part, Express provides everything you need in an easily deployed, lightweight node module that can be downloaded from Node Package Manager (NPM).
