npm = node package manager

Bower - package manager
REACT - can use it native with the MEAN stack
expo.io - build apps on top of react

BELOW IS THE HISTORY FROM TERMINAL OF OSX:

===========INSTALLING NODE.JS, SETTING UP MEAN STACK!!++++++
https://scotch.io/tutorials/setting-up-a-mean-stack-single-page-application
527  cd meanexample/
528  touch package.json
529  git clone https://github.com/linnovate/mean.git
530  ls
531  cd mean
532  npm install && npm start # DIDN'T WORK, B/C you need "brew"

^^^^^^ DIDN'T WORK!!!...so the below needed to be done:

# INSTALL brew:
# https://changelog.com/posts/install-node-js-with-homebrew-on-os-x
533  /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"



# INSTALL NODE.JS and NPM, then do some "fixing" based on what brew told me: 
536  brew install node
537  brew update
538  brew doctor
539  brew install gettext libidn2 libunistring # fixing
540  brew doctor
541  export PATH="/usr/local/bin:$PATH"
542  brew install node
543  brew reinstall node # fixing
544  npm install -g grunt-cli # suggested to test if things worked

^^^ THE ABOVE INSTALLs NODE.jS AND NPM



# MESSED UP INSTALLING , then had to remove them:
545  npm install && npm start
546  ls
547  vi package.json 
548  vi server.js 
549  vi package.json
550  node server.js
551  ls
552  rm *
556  rm -r config
558  rm -r server src
562  vi package.json
563  ls
564  clear
# END MESS UP

# FRESH START:
# Content of files: package.json, server.js, nerd.js, index.html is in:
