Stop the Node.js Chaos! Master Multiple Versions with NVM

*🤯 Stop the Node.js Chaos! Master Multiple Versions with NVM! 🚀*

Are you tired of version conflicts when jumping between development projects? This video introduces you to the essential developer tool: *Node Version Manager (nvm)**. NVM is a powerful, **POSIX-compliant bash script* designed to help you *manage multiple active node.js versions* easily and efficiently.

NVM allows you to **quickly install and use different versions of node via the command line**. Watch how simple it is to switch between environments, for example, moving instantly from node `v16.9.1` to `v14.18.0`.

*✨ NVM Key Superpowers for Developers:*
*Version Switching:* Use `nvm use` to select any installed version.
*Instant Installs:* Download, compile, and install the latest Node version using `nvm install node`. You can also install specific versions like `nvm install 14.7.0`.
*LTS Support:* Easily reference Long-Term Support versions using aliases like `lts/*` or `lts/argon` when installing or using Node.
*Contextual Configuration:* Use a *`.nvmrc` file* in your project root to specify a required Node version (e.g., `5.9` or `node`), and NVM will automatically use or install that version when you run `nvm use` or `nvm install`.
*Setting Defaults:* Configure a default Node version for all new shells using `nvm alias default node`.

*🛠️ Installation and Environment*
NVM works on any *POSIX-compliant shell* (sh, dash, ksh, zsh, bash), and is compatible with platforms including macOS and Windows WSL. The recommended way to install or update NVM is by running the install script using `curl` or `wget`. After installation, verify it's working by running `command -v nvm`!

If you're migrating to a new Node version, NVM can even help *migrate your global npm packages* using flags like `--reinstall-packages-from=current`.

*🛑 Troubleshooting Note:* If you're on a Mac with an **Apple Silicon chip**, you might need special steps, including running a shell using Rosetta (`arch -x86_64 zsh`), to install older versions of Node prior to v16.0.

The Node Version Manager project is the primary method for managing Node versions on systems where it is supported, helping you maintain consistency across all your development workflows.
