is it accurate to say that coroutines are kotlins implementation of green threading or is it different/ more than that?

Hi Patrick following the wikipedia defintion

In computer programming, green threads are threads that are scheduled by a runtime library or virtual machine (VM) instead of natively by the underlying operating system.

I would say that Java Threads are "green threads" Coroutines are much more than that. They are basically a toolset for asynchronous programming which gives you not only concurrency but also continuation and suspension there is actually a very good tak from Roman Elizarov from Kotlinonf 2018

Java `Thread`s aren't green they're scheduled by the OS, not the JVM.

Thanks for the Info Karel 🙂

I would say the difference is coroutines normally function via cooperation rather than random-ish interruption
