Installation

Ensure you have Node version >= 6 installed

> node --v
v6.0.0 # at least 6.0.0 is required

Ensure you have a javascript package manager such as npm or yarn installed.

The version numbers don't matter so much, just ensure that you have something installed.

> npm -v
5.5.1
> yarn -v
1.3.2

Once that's out of the way, install the application specific dependencies and run the application. You can use either npm or yarn to run these commands. I'll use yarn.

> yarn install

To start the application:

> yarn start

Navigate to http://localhost:8080 in your browser.

Get JP to the Balloon

The point of this simple game is to get JP to the balloon. The game works pretty well, but there's also a bug or two.

Your job is to complete the unit tests in the functions.test.js file and to make any necessary changes to the code in the functions.js file so that all those tests pass.

You can find those files here:

/app
  functions.js
  functions.test.js

Run the tests now and check the output in the console.

> yarn test

You may find it useful to have jest, the test framework we are using, "watch" your code and continually run your tests as you make changes (you can press q to quit at any time):

> yarn test-watch // or npm run test-watch

You'll notice that the unimplemented tests start with it.skip. You'll want to remove the .skip part as you complete each test.
