Kotlin: coroutines basics

Example:

Copy Code
fun main() {
    launch {
        delay(1000L)
        print("World!")
    }
    print("Hello, ")
}

Coroutines provide a way to write asynchronous code in a sequential manner.

Solution:

Copy Code
import kotlinx.coroutines.*

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