Hello world is a very simple computer program that simply displays that message to the screen. Traditionally, introductory computer programming lessons or tutorials begin by teaching how to write a hello world app in a given language.
While the amount of code it takes to write hello world in a given language is a fairly meaningless measure, I find it interesting to compare various popular (and not so popular) languages, and see how much work they require for this most trivial applications.
