version management
===================================================================================================================================

## nvm

can use nvm to manage nodejs versions.
not really sure how this works, but it is per user and operates off bash scripts and variables ¯\_(ツ)_/¯

going to have to pull from github. It will curl to clone the repo and then add some stuff to your bashrc to make it work.
`exec bash` after install to refresh

nvm install --lts
nvm use version

## npm n helper

npm can be used to manage node itself through n

sudo npm cache clean -f


1. setup & *own* directyory with versions 
   * `sudo mkdir -p /usr/local/n`
   * `sudo chown -R $(whoami) /usr/local/n`
2. own the instalation folders
   * `sudo chown -R $(whoami) /usr/local/bin /usr/local/lib /usr/local/include /usr/local/share`
3. install n: `sudo npm install -g n`
