Modules

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.

When hiring Ruby on Rails programmers, knowing the right questions to ask during an interview was a real challenge for me at first. In 30 minutes or less, it's difficult to get a solid read on a candidate's skill set without looking at code they've previously written. And in the corporate/enterprise world, I often don't have access to their previous work.

To ensure we hired competent ruby developers at my last job, I created a list of 15 ruby questions -- a ruby measuring stick if you will -- to select the cream of the crop that walked through our doors.

What to expect

Candidates will typically give you a range of responses based on their experience and personality. So it's up to you to decide the correctness of their answer.

The game we're building is a simple side-scrolling racing game. The player's car is static on the screen, only the background is moving. The enemies are planes whom the player must dodge using the up and down arrow keys. If the player hits a plane, he dies. One point is given each time a plane goes off screen without touching the player.

Sprites

Our game is composed of sprites. Each sprite has a position (x, y), velocity (speed) and one image, or more if animated.

Images are loaded from the DOM using their CSS selector (imagesSelector). We use ID selectors (#name) for single images and class selectors (.name) for animated sprites composed of several images.

See the images used in the game.
