What is Node.js?

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a web browser. It allows developers to build scalable network applications and has gained widespread adoption due to its non-blocking, event-driven architecture, which makes it ideal for real-time applications.

Talking about Node.js Libraries and Packages

Node.js libraries, often referred to as packages or modules, are collections of reusable code that extend the functionality of Node.js. These libraries can be easily integrated into Node.js applications using package managers like npm (Node Package Manager) or yarn, enabling developers to leverage existing solutions and accelerate their development process.

Before you start with this, you must know everything you should know for Node.JS as a Backend.

Before diving into the next section, ensure you’re solid on full-stack development essentials like front-end frameworks, back-end technologies, and database management.
