Kotlin coroutines offer several advantages over RxKotlin/RxJava for asynchronous programming:
Simpler API: Coroutines use the suspend modifier and Flow to represent asynchronous streams, which is much simpler than RxJava's multiple stream types like Observable, Flowable, Maybe, Single, and Completable[3][4]. This makes the API easier to learn and use.
Easier to write custom operators: Creating custom operators in RxJava is complex due to factors like backpressure, while Flow operators in coroutines are typically just written like normal code[4].
Structured concurrency: Coroutines use structured concurrency, making it easier to manage the lifecycle of concurrent code compared to RxJava streams which can lead to leaks[1][4].
Kotlin multiplatform: Coroutines work on any Kotlin-supported platform, allowing sharing of asynchronous code between Android and iOS, while RxJava is limited to Java[1][4].
Lightweight and efficient: Coroutines are more lightweight and efficient than RxJava, using less memory which leads to better performance and battery life on Android[5].
