Learn Node.js
From Scratch
Node.js lets you run JavaScript on the server. Build fast, scalable network applications with its event-driven, non-blocking I/O model. Master modules, HTTP, file system, and database integration.
Node.js is an open-source, cross-platform JavaScript runtime environment built on Chrome's V8 engine. Created by Ryan Dahl in 2009, it allows JavaScript to run on the server side. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications. It powers popular frameworks like Express.js and is the backbone of the MEAN/MERN stack.
