nvm nodejs

NVM (Node Version Manager) is a command-line tool that allows you to easily switch between different versions of Node.js on your computer. It helps manage multiple versions of Node.js and makes it convenient to switch between them based on your project requirements. With NVM, you can install, uninstall, and use different versions of Node.js side by side.

To install NVM and Node.js, you can follow these steps:

1. Open your terminal.
2. Visit the NVM GitHub repository (https://github.com/nvm-sh/nvm) and follow the installation instructions for your operating system.
3. Once NVM is installed, close and reopen the terminal to make sure it's correctly detected.
4. To install a specific version of Node.js, use the following command:

   nvm install <version>

Replace `<version>` with the desired Node.js version, such as "14.17.0" or "16.3.0". This will download and install the specified version.
5. To use a specific version of Node.js, you can set it as the default with:

   nvm use <version>

Replace `<version>` with the desired Node.js version. This will make the specified version the default one for your terminal session.
6. You can verify the installed version of Node.js using:

   node --version

This command will display the currently active version.

Remember to consult the NVM documentation for more advanced usage options and troubleshooting, as it provides extensive information on managing Node.js versions with NVM.
