What is Node.js?

JavaScript on the Server

Node.js is a powerful, open-source runtime environment that allows developers to run JavaScript on the server side. Built on Chrome’s V8 JavaScript engine, it enables fast and scalable backend development using JavaScript.


With its event-driven, non-blocking I/O model, Node.js excels at handling multiple concurrent connections efficiently. It’s perfect for building real-time applications, APIs, web servers, and microservices.

NPM

The Node Package Manager

NPM is the world’s largest software registry and the default package manager for Node.js. It allows developers to discover, install, and manage JavaScript packages with simple commands.


With over a million packages, NPM makes it easy to add powerful features without reinventing the wheel. It handles dependencies, versioning, and publishing, making collaboration and code sharing seamless.


Whether you’re building a small script or a large enterprise app, NPM is the backbone of the modern JavaScript ecosystem.
