> Note: AssetBundleRequest has `asset` and `allAssets`, default await returns `asset`. If you want to get `allAssets`, you can use `AwaitForAllAssets()` method.
The type of `UniTask` can use utilities like `UniTask.WhenAll`, `UniTask.WhenAny`. They are like `Task.WhenAll`/`Task.WhenAny` but the return type is more useful. They return value tuples so you can deconstruct each result and pass multiple types.

`UniTask.WhenEach` that is similar to .NET 9's `Task.WhenEach` can consume new way for await multiple tasks.
```csharp
await foreach (var result in UniTask.WhenEach(task1, task2, task3))
{
// The result is of type WhenEachResult<T>.
// It contains either `T Result` or `Exception Exception`.
// You can check `IsCompletedSuccessfully` or `IsFaulted` to determine whether to access `.Result` or `.Exception`.
// If you want to throw an exception when `IsFaulted` and retrieve the result when successful, use `GetResult()`.
Debug.Log(result.GetResult());

UniTaskAsyncEnumerable implements asynchronous LINQ, similar to LINQ in `IEnumerable<T>` or Rx in `IObservable<T>`. All standard LINQ query operators can be applied to asynchronous streams. For example, the following code shows how to apply a Where filter to a button-click asynchronous stream that runs once every two clicks.
