Homebrew
We'll be using Homebrew as package manager for installing node. Homebrew gives us more control than say, the default Mac installer.
In order to install Homebrew we need to pull the latest installation script from the website. Open a terminal app and install the application with the following command:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Formulae can be installed with the install command:
brew install [package]
