Node Js

Node.js lets you run JavaScript outside the browser, primarily for building back-end services, tools, or full-stack applications.

Node Installation

Check version

node -v

npm -v

nvm -v

Option 1: Install from Official Website

• Go to: https://nodejs.org
• You’ll see two options:
  • LTS (Long-Term Support) – Stable, recommended for most users
  • Current – Latest features, but may be less stable.
• Download and install the LTS version.

This installs both Node.js and npm (Node Package Manager).
