Which tool for asynchronous programming are you more familiar with – RxJava or Coroutines?

I am familiar with both RxJava and Kotlin Coroutines, but I more often use Coroutines because they are more native to Kotlin and Android.

RxJava is a library for reactive programming based on data streams and transformation operators. It is powerful but can be complex to understand and debug.

Kotlin Coroutines is a language feature for asynchronous programming, allowing you to write asynchronous code in a sequential style using suspend functions and launch/async coroutines.

Example with Coroutines:

import kotlinx.coroutines.*

fun main() = runBlocking {
    launch {
        delay(1000L)
        println("World!")
    }
    println("Hello")
}

Coroutines integrate more easily with Kotlin, have a lower learning curve, and are better suited for most tasks in Android development.
