Zipping analogy with Coroutines

DataManger.kt

private val zipDataChannel = Channel<List<FeedItem>>(2)

// Async coroutine builder for latest movies
fun loadLatestMoviesAsync() =
   scope.async(coroutinesDispatcherProvider.io) {
     moviesRepository.getLatestMovies()?.let {
       zipDataChannel.send(it)
     }
   }
// Async coroutine for popular movies
fun loadPopularMoviesAsync() =
   scope.async(coroutinesDispatcherProvider.io) {
     moviesRepository.getPopularMovies()?.let {
       zipDataChannel.send(it)
     }
   }
// Consuming the zipped data and sending in callback
fun zipMovieResults() = scope.launch(coroutinesDispatcherProvider.io) {
  for (values in zipDataChannel) {
    totalResults.add(values)
  }
  onDataLoadedCallback?.onDataLoaded(totalResults)
}

ViewModel.kt

private fun zip(vararg anyObjects: Unit?, call: (Any) -> Unit) {
  call(anyObjects)
  // closes channel
  dataManager.closeChannel()
}

private fun loadData() = scope.launch {
// Await till these two call finishes
  zip(
       dataManager.loadLatestMoviesAsync().await(),
       dataManager.loadPopularMoviesAsync().await(),
   ) {
       // Consumes value from channel internally 
       dataManager.zipMovieResults()
    }
}
