I wish these types of projects would identify themselves as koans in the README or something. Makes it much easier to surface exercises like this when googling.

I think this is the best way to learn languages.

Does anyone know of any for TypeScript?

You're absolutely right. My own first exposure to this type of learning resource was Ruby Koans. I believe Rustlings (which was my direct inspiration) also credits RK. I'll update the README with the grandparent attribution. :-)

I love these sorts of resources! I just created an "awesome list" [1] to keep track of resources specifically centered around learning by example. I've only got a few so far, several of them being from this thread. Contributions welcome!

I saw your comments and I was thinking to myself.. "They should have one for Regex (regular expressions). That would be a cool way to learn it."

Apparently someone did. ¯\_(ツ)_/¯ TIL

I have regex101 open in a tab any time I am developing a regex :). It's an awesome tool, and I especially appreciate the mini language reference in the lower right corner of the window.

Regex101 is especially useful, I use it to check for catastrophic backtracking¹ before committing a regex.

Never heard of koans before, it’s a brilliant idea for learning a new language.

Opportunity for a index or site for koans.

Koans are a fairly well-known technique, and if you Google "<language> koans" you'll find something for most languages. I like it as a learning style.

Let's hope that nobody invents a language called Zen -- they will run into problems. :)

if you want to have a laugh, check the news section of ziglang.org. There was also a pretty big discussion on HN at the time.

Hah! I didn't know of any Zen languages -- just to find one a stone's throw away from Zig. Thanks for pointing that out.

(And that news story... what an absolute mess of a situation.)
