This script installs Node Version Manager (NVM) and sets up a default Node.js version on your system. NVM is a command-line tool that allows you to install and manage multiple versions of Node.js on the same machine.

Before running the script, you need to make sure that your system meets the following requirements:

• Unix-based operating system (e.g., Linux, macOS, or WSL on Windows)
• Bash or Zsh shell
• Curl command-line tool

To install NVM and set up a default Node.js version, follow these steps:

1. Clone or download the script to your local machine.

2. Open a terminal window and navigate to the directory where the script is located.

3. Make the script executable by running the following command:

chmod +x script.sh

4. Run the script with one of the following options:

• ./script.sh lts: Installs the latest LTS (Long-Term Support) version of Node.js and sets it as the default version.

• ./script.sh: Installs the latest version of Node.js and sets it as the default version.

5. Wait for the script to finish running. It may take a few minutes to download and install the selected Node.js version.

6. Once the script has finished running, you should be able to use the node and npm commands in your terminal.

After running the script, you can use NVM to manage your Node.js versions by using the following commands:

• nvm install <version>: Installs a specific version of Node.js.

• nvm use <version>: Switches to a specific version of Node.js.

• nvm ls: Lists all installed versions of Node.js.

• nvm alias <name> <version>: Sets an alias for a specific version of Node.js.
