This is a lecture on coroutines in the Kotlin language. 
Kotlin's usage has been increasing recently. Google announced that more than 70% of the top 1,000 apps on Google Play use Kotlin. As the Kotlin language grows, the Kotlin language itself is also evolving. 
The Coroutines feature, which was added relatively recently, provides groundbreaking features that were previously unprecedented. 
However, its novelty is also great. Fortunately, I was able to organize Kotlin's coroutines through many materials scattered online and kotlinlang.org.
