Using nvm

What is nvm?

nvm is a Node Version Manager. It's perfect for running multiple versions of Node.js on the same machine.

Installing nvm

:::warning If you've already installed Node.js on your machine, uninstall Node.js before installing nvm. This will prevent any conflicts between the Node.js and nvm.
