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 

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
https://github.com/tj/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`
