// Notes in comments:
// 1. Task.FromResult is a way to return a completed task with a given result.
// 2. ValueTask is a struct (value type), so it doesn't have the heap allocation overhead of Task (which is a class/reference type).
// 3. Using ValueTask can be beneficial when you want to minimize allocations, especially in high-performance scenarios.
