“Stuff I always forget how to do and have to google it”

The main difference between async vs launch is that async can return a value and launch cannot

On Async statement

runBlocking {
    val job = async {
        println("Running on the background!")
        Thread.sleep(1000)
        "this is done!"
    }

    println("Response is ${job.await()}")
}

This will print “Response is this is done!”

Similar thing on Launch statement

runBlocking {
    val job = launch {
        println("Running on the background!")
        Thread.sleep(1000)
        // "this is done!" -> useless statement :(
    }

    // -- await() doesn't work :(
    // println("Response is ${job.await()}") 
    job.join()
}

How to return a value from launch statement

It is some extra work but can be done, check previous channels post about this:
