Concurrency made easy with Kotlin Coroutines

" summary

Shows that Kotlin Coroutines use the suspend keyword and transform functions into resumable state machines, replacing Thread.sleep with delay vs Thread.sleep nonblocking suspension so a pasta demo drops from 35s to 20s on one thread. Explains structured concurrency, scopes and error propagation, GlobalScope pitfalls, runBlocking for bridging and dispatchers (Default, IO, Main), demonstrates a Spring WebFlux + R2DBC reactive web app where coroutines are the glue, and claims thousands of coroutines with far less memory than 100k threads.
