But I think it is the coroutine who gets suspended because it is waiting for the function to finished? "suspend" usually means "cease operation", in this case the

问题 Can Kotlin coroutines be used in production, and what does their experimental status mean? 回答1: UPDATE : Kotlin coroutines are no longer experimental as of Kotlin 1.3. Kotlin coroutines can and should be used in production. That was the chief reason to officially release them in Kotlin 1.1. Having released them, the JetBrains team had committed to maintain backwards compatibility with respect to any changes that are introduced to them in the minor releases as they evolve, while allowing
