suspend fun jobLifecycle () = coroutineScope {
   val job =  launch{
       println("Working....")
       delay(2000L)
       println("Done !")
    }

    delay(1000L)
    job.cancel() 
    // delay(1L) i have to do it to print correct value of job.isCompleted below

    println("isCompleted: ${job.isCompleted}") // it is printing "false" but if i delay for some time after cancelling the job it prints  "true".

}

is it my computer or it really takes some time to move job from cancelling to cancelled state where isCompleted becomes true after cancellation of job or is there something i'm missing out please review🔦

Job.cancel is not a suspending function, which means that calling it will not immediately interrupt the associated coroutine.
AFAIK it will transition that coroutine to the Cancelling state, which is not considered completed yet. There is a slight delay before that coroutine moves to the Cancelled state ; your hardware is probably not in cause 😉

You can wait for cancellation by join()-ing the job after calling cancel(), or do both in one go with cancelAndJoin() - this is a suspending function, and isCompleted will be true afterwards
