title: Difference between NPM and NVM
body: <p>I know <strong>npm</strong> is the package manager and <strong>nvm</strong> is the node version manager. I am currently trying to auto-install my development and production environment using Bash and forgot how I started out and in what order. After installing npm, I found our nvm was not installed. </p>
  
  <p>Do I still need to install nvm? If so, what is the benefit?</p>
