I've always created small, self-contained tests when learning a new programming language or feature, going all the way back to when I was a kid. I can't recommend enough how valuable it is to make these yourself. The depth of learning you get when trying your damnedest to break a system is invaluable!
I used to not keep these tests. Curiosity satisfied, I'd often just chuck 'em, but after having had to remake quite a few over the years, I've learned that they make great notes, no matter how trivial they seem.
Please feel free to explore, learn, and use them as a reference of your own.
The easiest way to run these tests is with Node.js. Clone the repo and run any script using:
node filename.jsThe real value is in reading the code and comments alongside the debugger output.

Happy coding!
