homebrew

• Software Installer for mac
• Install from brew.sh
• Always brew update && brew upgrade
• It looks for a formula (software) you want to install, grab the installation script from repo, then execute the installation
  • If the formula is from homebrew-core repo, that means the app you want to install is actively maintained by the core team
  • Else, you will need to brew tap <repo-name> before you brew install <package-name>

Node JS

• Use Node Version Manager (NVM): brew install nvm
• nvm install 8.11.3 or whatever version number

NPM

• npm (node package manager) is itself a node package. Therefore it is available after you install Node. You can update npm by doing npm i -g npm.
• npm i -g <node package> installs a package globally
• npm i <node package> installs a package in current folder with the existence of package.json

rbenv

• brew install rbenv
• rbenv install <ruby version>
• rbenv global <ruby version>
