# 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: ```text _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 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 JavaScript to install the necessary dependencies: http://exercism.io/languages/javascript/installation ## Running the test suite The provided test suite uses [Jasmine](https://jasmine.github.io/). You can install it by opening a terminal window and running the following command: ```sh npm install -g jasmine ``` Run the test suite from the exercise directory with: ```sh jasmine queen-attack.spec.js ``` In many test suites all but the first test have been marked "pending". Once you get a test passing, activate the next one by changing `xit` to `it`. ## Source J Dalbey's Programming Practice problems [http://users.csc.calpoly.edu/~jdalbey/103/Projects/ProgrammingPractice.html](http://users.csc.calpoly.edu/~jdalbey/103/Projects/ProgrammingPractice.html) ## Submitting Incomplete Solutions It's possible to submit an incomplete solution so you can see how others have completed the exercise.
