Tetris is a classic game. In this article by Stefan Björnander, we will develop a version very similar to the original version.

The first step in protecting web services is to authenticate and authorize the web service requests. Authentication in web services is the process of verifying that the user has valid credentials to access the web services and authorization is the process of validating that the authenticated user has appropriate privileges to access the web services.

It's one of these things in JavaScript (closures are another) which, once you "get" them, they seem so obvious and make perfect sense. As with the rest of the article, you're strongly encouraged to type in and play around with the examples; this makes it much easier to learn and remember the concepts.
