In JavaScript, objects can be used to serve various purposes.

To maximise our usage of the type system, we should assign different types to our objects depending
on the desired purpose.

(aka maps), and how they can both be used with regards to the type system.

Install Multiple Java Versions on macOS High Sierra

Install Homebrew Cask

On Mac, Homebrew is the de-facto package manager, and Homebrew Cask is the app manager. I’m going to use Cask to install Java 7 and 8.

Install Homebrew Cask first if you haven’t:

brew update
brew tap caskroom/cask
