Is there any difference between `.conflate().map { … }` and `.conflate().mapLatest { … }`?

yes. in first case map's body will be processed (for each non-conflated item), while in second it will be cancelled if new item appear.

```    flow {
        repeat(20) {
            emit(it)
            delay(100)
        }
    }.conflate()
        .mapLatest { // change to map to see difference. 
            delay(250)
            it
        }.collect {
            println(it)
        }```
If map's body is perfectly supports cooperative cancellation, there is no `conflate()` necessary.

Thanks, so `mapLatest` makes the `conflate` pointless and not the other way round :+1:

Kinda, you can change `delay` in map to `Thread.sleep` and you will see that conflate  may be important even with `mapLatest`
