Is somebody able to share an explanation for why the test below prints

9a

9b

9c

9d

9e

9f

when it seemingly should be printing

1a

2a

3a

4a

5a

6a

7a

8a

before that?

@Test
    fun example1(): Unit = runBlocking {
        val flowA = flowOf(1, 2, 3, 4, 5, 6, 7, 8, 9)
        val flowB = flowOf("a", "b", "c", "d", "e", "f").onEach { delay(1000) }

        flowA.combine(flowB) { a, b -> "$a$b" }.collect { println(it) }
    }

Because combine uses the most recent values: https://kotlinlang.org/docs/reference/coroutines/flow.html#combine

[Shalom Halbert]

Ah, didn’t give attention to the impact of a delay on the first value of flowB. Thank you 🙌
