Hey, the author here.

Agree, I wasn’t consistent with “a framework” vs “just language” approach. Ideally it should be 100% one or another.

My idea was to use the standard library as much as possible, but I didn’t eliminate the use of third party libraries entirely if it would allow async/concurrent processing.

It all started with Go vs Rust vs Zig as the main point of comparison. Then I added more languages I am familiar with.

By far, IMHO, Go is a clear winner in terms of being 100% with the standard library, fully concurrent and quite concise.

Sure, JS/TS implementations are also concise but it is different, not natively compiled technology.

The language's selection is purely my personal familiarity, so nothing wrong with Java, it’s just not my area.
