# Queen Attack

Given the position of two queens on a chess board, indicate whether or not they
are positioned so that they can attack each other.

In the game of chess, a queen can attack pieces which are on the same
row, column, or diagonal.

A chessboard can be represented by an 8 by 8 array.

So if you're told the white queen is at (2, 3) and the black queen at
(5, 6), then you'd know you've got a set-up like so:

```plain
_ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _
_ _ _ W _ _ _ _
_ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _
_ _ _ _ _ _ B _
_ _ _ _ _ _ _ _
_ _ _ _ _ _ _ _
```

You'd also be able to answer whether the queens can attack each other.
In this case, that answer would be yes, they can, because both pieces
share a diagonal.

## Setup

Go through the setup instructions for ECMAScript to
install the necessary dependencies:

http://exercism.io/languages/ecmascript/installation

## Requirements

Install assignment dependencies:

```bash
$ npm install
```

## Making the test suite pass

Execute the tests with:

```bash
$ npm test
```

In the test suites all tests but the first have been skipped.

Once you get a test passing, you can enable the next one by
changing `xtest` to `test`.
