Would love the equivalent of this but before applying practical problem solving. For instance in go you learn to leverage goroutines and channels. In another language it would be threads. Common design patterns etc. Gotcha’s of the language. In Python you use exception handling very commonly, in golang you’re using a special return value of an error type. JavaScript you’re using a ton of anonymous function closures. Async vs await.

I keep wanting to build this mega doc site to teach more than just “what are scalar types in this language” and more of how to apply it in idiomatic ways.

This is excellent. I checked Julia which is my main language and all essentials are there. Looked up to Zig, F#, Go all accessible expositions and makes it easy to get a good taste before looking into the manuals.
