To Play the game:

• yarn to install npm modules
• then yarn start to start a new game

if you don't have yarn, here's how to install it:

brew install yarn or sudo port install yarn

To run tests:

• yarn test:unit
• if using WebStorm's test runner (like I do), all you need is to set it to the unit test directory then add this for mocha options: --recursive -r @babel/register ./src/test/test.imports -w

Implementation Notes

The modules in this game are all done via JS Closures.
