Shenandoah in OpenJDK 17: Sub-millisecond GC pauses

Incorrect, Swift is not garbage collected. It uses reference counting. Read more here: https://docs.swift.org/swift-book/LanguageGuide/AutomaticRef...

As for C and C++, yes, of course. I meant "everyone else" as in the trendy new languages.

Reference counting is technically a form of garbage collection, FYI.

Reference counting deals with operations that have constant time, which I think puts it in a different category than what people normally view as GC.

And has a different tradeoff, due to atomic operations being needed for objects shared between threads (and of course, circular references).

But no matter what, it is literally a GC algorithm, described in every book about GCs.

I'm not sure that's true. Python mainly uses RC, yet most people think of Python as GC'd. I would argue that most people think that GC == automatic memory management.

Yes, I think you are correct actually.
