Asynchronous and Concurrent Programming in Scala Part 3
summary
Workshop shows using ZIO to build concrete asynchronous, concurrent code: modules with ZIO environment that get provide/provideSome wiring, helper APIs that let Scala infer effect types, and a small console guesser that compiles, runs under test clock/test random/test console, and is fully testable. Covers fibers not OS threads, fiber refs, promises, queues, semaphores, streams and schedulers, and claims you can run 100k+ lightweight fibers with deterministic, leak‑free behavior and interruption-friendly primitives.
