Kotlin Coroutines: Beyond async/await
summary
Kotlin implements concurrency by pushing behaviour into libraries so code uses one keyword: suspend while async and await are ordinary functions that return deferred as future objects. The compiler turns suspend points into a state machine with resume/resumeWith semantics; Retrofit integrates via a Retrofit call adapter that yields Deferred and an await extension. Coroutines run lightweight workloads (demonstrated with 100,000 coroutines), support channels, cooperative cancellation via Job, and practical helpers like retryIO and lifecycle-aware cancellation.
