Test-driven development is A Good Thing. There are many sites out there that will give you abstract discussions on why you should be doing it, so this page won?t dwell too much on that.

SUSIE is a simple application and shows a side of Ruby that other programming languages lack, the ability to be straight forward and small. Ruby does have muscle and lots of it.

One of the coolest things I ran across in RJS was the delay method. This delay method will do just that and delay a number of seconds. So lets say you need to highlight something that was just added to the page after the user submits it. I would like it to add to the page then wait 1 second and then highlight. The following is the code for that.
