Hello world is valid for checking that you have everything installed properly and it's the fastest way to make sure you get the most basic syntax of the program.

It's not like the first thing you're going to do is write out all of quicksort to see if it's easy. You're going to fiddle with numbers an arrays a bit first, particularly if your language has some kind of interactive console. In fact, I wouldn't be surprised if the first thing you do in the language is actually 1+2.

There's quite a bit of syntax you need to learn before quicksort becomes a relevant test.

If you're looking for a good language to build a quick website backend in you probably don't even care about that, you'll care more about having nice ways of passing information around and checking that it has a decent inbuilt sort method.
