Node.js on Ubuntu 26.04

Node.js is an open-source, cross-platform JavaScript runtime built on Chrome’s V8 engine, designed for building fast and scalable server-side and network applications. It uses an event-driven, non-blocking I/O model that makes it highly efficient and suitable for real-time and high-performance workloads.

Features of Node.js:

• Node.js provides a lightweight and efficient architecture ideal for developing APIs, web applications, and microservices using JavaScript on the server side.
• Its non-blocking, event-driven model enables handling of thousands of simultaneous connections with excellent performance.
• It includes a rich ecosystem of libraries via npm (Node Package Manager), allowing developers to quickly integrate packages like Express.js, NestJS, and Socket.io.
• Node.js makes backend development easier by enabling full-stack JavaScript development, reducing context switching and improving developer productivity.
