1. Update Package Lists:

• sudo apt update
  This command updates the local database of available packages and their versions from the repositories.

2. Install Curl:

• sudo apt install curl
  Curl is a command-line tool used to transfer data to or from a server. It's used here to download the script for setting up Node.js.

3. Download Node.js Setup Script:

• sudo apt install
• curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
  This command uses curl to retrieve the setup script for Node.js LTS version from the NodeSource repository. The -fsSL flags tell curl to fail silently on errors, follow redirects, and show progress in a user-friendly way. The script is then executed using sudo -E bash - to set up the repository for Node.js.

4. Install Node.js and npm:

• sudo apt install nodejs
  After running the setup script, this command installs Node.js and npm (Node Package Manager). Node.js is the runtime environment for executing JavaScript code, and npm is a package manager for Node.js modules and libraries.

5. Verify Installation:

• node -v
  This command checks the installed Node.js version and displays it in the terminal.
• npm -v
  Similarly, this command checks the installed npm version and displays it in the terminal.
