Job

A job is a fire-and-forget task. An operation that, once started, you will not be waiting on, unless, maybe, there's an exception. The most common way to create a job is to use the launch() coroutine builder, as shown:

fun main(args: Array<String>) = runBlocking {
    val job = launch { 
        // Do background task here
    }
}

However, you can also use the Job() factory function, like this:

fun main(args: Array<String>) = runBlocking {
    val job = Job()
}
