Hi there, is there any way a can rum multiple coroutines in parallel then resume when all of then are completed ?
Something like that.
```viewModelScope.launch {
    launch { a = one() }
    launch { b = two() }
    print(a+b)
}```


Use async and then await to wait for result of both

```coroutineScope {
    launch { a = one() }
    launch { b = two() }
}
print(a + b)```

although if you're not using them elsewhere, async/await could let you get rid of `var a/b`

`val sum = async{one()}.await() + async{two()}.await()`

nope, order of operations there makes them run serially

```val sum = listOf(async { one() }, async { two() }).sumOf { it.await() }
```
if you really wanted to avoid temporary values for some reason… otherwise
```val a = async { one() }
val b = async { two() }
val sum = a.await() + b.await()
```
works straightforwardly
