" summary

Project Loom brings virtual threads to Java as an alternative concurrency model for asynchronous programming. It explains that virtual threads are lightweight, JVM-managed threads that can be created and handled in very large numbers, describes the new language/runtime concepts developed so far, and discusses when to use virtual threads versus traditional OS threads.
