Ask HN: What is the first thing you do when trying a new programming language?

Or perhaps more specifically, for some of us: what is the first thing you write when experimenting with a new language?

Whenever I am trying out a new language, I like to tinker around sort of aimlessly, meandering about picking up on intricacies until I feel temporarily fulfilled. But I imagine that some, if not many, of us like to jump right into something specific that helps to provide us with some level of insight that we crave.

So what is the first thing that you write, trivial or otherwise, when you first get your hands on a programming language? What is that first technique you try, that first structure you implement, that first algorithm you hammer out? Is there a certain function or method you like to tackle? Or do you just explore without any real direction?
